Academic and research background
The desire to know more about the nature has motivated me to step into the broad world of science. I have cultivated my great interest in physics, chemistry, biology and a lot of related fields since I was very young. I was armed with strong foundation in physics due to my three years’ time in Tianjin Nankai High School, (one of the most famous high schools in China).
In the September of 2000, I entered University of Science and Technology of China and became a member of physics department since then. New environment always brings unexpected difficulties, and great effort has given by me to get adapt to the new life. During the period of hard trying, both my knowledge and my maturity have remarkably grown and I finally got rank above 12 % of 140, with overall GPA 3.5/4.0, and major GPA 3.8/4.0. My hard working finally earned me the Outstanding Student Scholarship in 2003.
Besides enhancement of knowledge in physics, I have also accumulated a great deal of knowledge in chemistry and material science. I have got 95/100 in “The Structure and Properties in Solid and Solid State Chemistry” and 87/100 in “Solid State Optics and Spectroscopy”, among the top scores in class. Moreover, I have made effort to improve my ability in mathematics and computer science cautiously.(附加的段)
My two years’ research in Structure Research Laboratory of USTC has brought me to a more extensive and practical field of physics. Served as an undergraduate research assistant in Professor Xianhui Chen’s group, I have devoted most of my time to the research and my knowledge in condensed matter physics and its related fields have greatly increased. I have obtained all the basic experimental skills in a very short time and in order to keep with the pace of the latest achievement in my research field, I have spent a large amount of time in reading related journals, such as Appl. Phys. Lett., J. Appl. Phys., Phys. Rev. B, Phys. Rev. Lett., J. Solid State Chem. and so on.
At the beginning of 2003, I began my systematical work in exploring the growing method and transport property investigations in hole-doped single crystal BSLCO (Bi2Sr2-xLaxCuO4+y) series and electron-doped NCCO (Nd2-xCexCuO4-y) series. My work was focused on the single crystal preparation and physical property measurement, especially the transport property and magnetic properties. After so many times of attempt in the melting range and descending speed, I successfully grew a great deal of single crystals with high quality. Moreover, I have spent so many days and nights together with my colleagues in lab measuring the resistance of the single crystals under zero field and high field. Due to the high quality of the crystals and our hard work, we finally obtained plenty of meaningful data and by analyzing the normal state property, I have submitted a paper titled “Field-induced log (1/T) diverging resistivity deviation from normal state in superconducting cuprates” to Phys. Rev. Lett. in 2003 as the third author. However, my work was not stopped and with further investigation in the 2D weak localization system, I have submitted another paper to Europhys. Lett. in October 2003 as a co-author.
Besides, through the work, I obtained almost all the skills of manipulation of the corresponding instruments from physical preparation to characterization, such as M.Braum Glove-Box system (Germany), MORRIS High Pressure system (Berkeley), Rietveld and Lebail Refinement of crystal structure from XRD pattern, 17 T Ultra-High Magnetic Field system (Oxford Science), AC Assistance Bridge (Liner Research Inc.) sputtering and so on. What’s more, I can skillfully use software, (GSAS, FullProf, CELL PCPDFWIN and etc), to analyze the structure of the material through X-ray diffraction data.
Beyond the achievement in research, the happiness I gained from the cooperation with others and the approach of the physics science was greater. Times of failure make me believe that the persistence is the only thing to make people gain their goals and the research work needs active and creative thinking. I often have discussion with other members in my group not only on the current encountered problem but also on the some new ideas for research. During the weekly group meeting, we often exchanged our views on our current research project and I have learned a lot through this communication.
Meanwhile, I never give up searching for more extensive and challenging field. Actually, some of my present work is from my own idea. Known the misfit layer of CoO2, I have grown some single crystals of highly efficient thermoelectric materials, such as Bi2Sr2Co2O, Bi2Sr2CoO6+y, Ca3Co4O9....... In order to find the relationship between the misfit structure of CoO2 layer and the high thermoelectricity, magneto-resistance and magneto-power, I have investigated the low-temperature transport, thermal and magnetic properties. By reading a number of related papers, I plan to take further investigation of these materials through their thermoelectric potential and other related measurements.
With great interest in nano science, I have paid extra attention to the update technique in synthesizing the nanowires and nanoparticles. Both from the corresponding books in this field and experience of the PhD students in my group, I grasped a number of methods, such as micro-emulsion, hydrothermal method, sol-gel and other soft chemical ways to synthesize the nano scale materials. Under the available condition, I am synthesizing the nano scale superconducting material YBCO and nanowires of magnetic materials, such as La0.5Ba0.5MnO3.
More and more do I realize the importance of collaboration, during my exploring of the novel polycrystalline Co1212 and Fe1212. The samples were reported by some group to be superconducting only if it is annealed under the extreme pressure. I have measured the transport property of the crystals and observed some abnormal phase transition of superconductivity. However, because of the limitation of experimental condition, our samples cannot become superconducting. In order to solve the problem, we cooperated with Institute of Physics of China Academic Science to obtain the extreme pressure. Two papers of my work on Co1212 have been submitted to the international journals late this year, and I was the second author. In this case, I realized the cooperation within and without a group is equally important, and sometimes accomplishment is gained under several groups of people. We also have done some work in YBCO thin film transport property, collaborated with professor C. L. Chen of Superconducting Center Texas, U.S.A.
In addition, I have also attended some of other sub-group’s research project, such as using sol-gel method to grow Ru1212, NaCoO2 transport property investigation and colossal magneto resistance materials preparation. What’s more, I have also attended the 7th National Superconductivity Conference and National Annual Conference of Physics in 2003. My ken was greatly enlarged by hearing the report of the attendance and my confidence in my research was increased at the same time.
Research interest and future plan
Material of science and engineering is concerned with the study of structure, properties and applications of materials. During my two years’ research in Structure Research Laboratory, I have accumulated plenty of knowledge in the related area of material science, and meanwhile my ability in doing research is greatly proved. In the past work, I have done quite a lot in synthesis as well as characterization, and I have also deal with different classes of materials, such as electronic, magnetic, superconducting and so on. I believe, aimed with strong foundation of physics, the appropriate area for me to take research work will be more extensive.
The area of interest is just as following:
1. I have read a lot of corresponding papers in magnetic recording research, and I have great interest in this kind of materials. I believe research in this area is important both for basic studies of the effects of dimensionality and interactions, and for the future of magnetic recording. Hence, I wish to do some work in synthesis and processing of this kind of materials.
2. Because nano materials, such as carbon nanotubes, nano particles, quantum dots, nano-porous structures, and nano-electronics device materials, are the essential part of the current and future nano-based technologies. I hope very much to continue my future research work in this area.
3. Moreover, I am also interested in the structural material, such as advanced engineering materials, which characters may be changed responding to the different mechanic condition. So I think I also hope to do the related research in analysis of materials property.
My future plan is to pursue my PhD degree in material science and engineering. In fact, though the technology is developing at a tremendous speed, there is still a lot of progress remaining to be made. For instance, nanoscale devices, either assembled lithographically or chemically, will have a high probability of failure. Therefore, any architecture built from large numbers of nano scale devices will necessarily contain a large number of defects, which fluctuate on time scales comparable to the computation cycle. Furthermore, deeper insight should be given into the constraints imposed by nano-devices, especially carbon nanotube-based devices, by modeling the devices and corresponding architectures. Such a framework can contribute towards building more powerful nano-probes, nano-computer and efficient power fuel-cells.
Why I Choose UCSD
UCSD is world famous for its outstanding faculty and reputation. Though the economic condition in California is not so satisfying at the moment, I believe it will not impede the future development of UCSD.
The Materials Science and Engineering Program at UCSD aims to provide fundamental knowledge for understanding of materials with the objective of predicting, modifying, and tailoring the properties of materials to yield, at the technology level, enhanced material performance. Also, I was greatly impressed by the great collaboration of different departments, which makes the Materials Science department more competitive and attractive. With so many outstanding professors and so broad research areas, I was convinced that the Material Science and Engineering Department is always the best choice for me to pursue my PhD degree.

Brought up in a shabby and cramped small apartment, I was fascinated in my childhood by the exquisite houses and condominiums I watched on TV in images that had been shot in the developed countries. It has since been my dream to build up in China the same kind of quality human habitat. I believe that this dream can come true if I get to undertake advanced studies in architecture at your university.
I am now erecting fundamental building blocks towards the realization of my dream at the Harbin Institute of Technology (known as HIT), from which I am scheduled to graduate next year. This elite institution accepted me in 1995 in recognition of my strong performance in the National University Entrance Examinations, held once every year nationwide to screen high school graduates for higher education. Here, I have received vigorous training in structure engineering, an area of study that is essential to the country's frenzied construction industry.
Deeply in love with my chosen area of studies, I have turned my mind into an engine of creativity during three years of disciplined learning. Courses of my major, particularly structure mechanics, architecture material, and survey of engineering, fascinate me so much that I am sometimes completely enthralled in studying them. Looking now at the reinforced concrete structures around me, I not only detect the configuration inside easily but also arrive at some preliminary assessment of its strengths and weaknesses quickly. Everything that comes into my sight presents itself in the framework of some form of structure. Carefully groomed as the only child in my family, I cannot stand being the second best in any group and situation, especially when it comes to a contest of intellectual caliber. At HIT, I beat the odds and excelled all most of my fellow students in academic studies, making myself the undisputed academic leader of the class. Students and faculty alike are so accustomed to my academic excellence that everybody would be surprised in class if I happen not to be able to answer a question better than others even once. My motto is : one either comes out the first, or he is a failure. The university has awarded me a string of scholarships and other accolades in praise of my academic achievements.
But I am no bookworm. In fact, I am constantly engaged in a host of extracurricular activities, for which I have been conferred a Special Commendation for Participation in Social Activities. I have run and won the position of monitor in my class during my first semester, which made me a natural student leader. Active on campus, I was then appointed the recreation officer of the Student Association, in charge of organizing entertainment and other recreational events for the benefit of the students. I now also serve as the president of the Society of Student Architects and Engineers. Such involvement in the student affairs has tempered my skills in leadership, organization and communication. But more importantly, it has broadened my horizon and deepened my insights in terms of what constitutes beauty, grace and strength, which I believe will always help me in my engineering designs.
I would like to mention here my passion for a uniquely oriental sport called weiqi, known as the go in the English parlance. An intricate chess game, it is challenging to even the best and brightest minds. One usually has to be a full-time player to play it well. Not to be daunted, I not only joined the Weiqi Club on campus but also taken part in a national contest, in which I won the 12th place and the HIT team I led won the 3rd place. My achievement in the weiqi sport testifies to my superior mental power and intellectual resourcefulness.
To tap fully into my intellectual resources, I would like to take up the greater challenges of helping to design my country's skylines in the 21st century. For that, I need better training that what I have received. An American education will expose mw to new perspectives and endow me with new inspirations. When I get to combine my Chinese perspectives with those of the West, I should have no trouble fulfilling my ambition of cutting one of the best structure engineers in the world. With that, I want to design and build the most beautiful structures in China.
To ensure both my future and that of my country's construction industry, I sincerely hope that I could be admitted into your university. I am confident that, if I can be lucky enough to study under your seasoned guidance and with your kind financial assistance, many people in China will never have to endure the kind of shabby and inconvenient apartments that I endured as a child.
