Dear x,
The desire to know more about the nature has motivated me to step into thebroad 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 wasarmed with strong foundation in physics due to my three years’ time in TianjinNankai High School, (one of the most famous high schools in China).
In the September of 20xx, I entered University of Science and Technology ofChina and became a member of physics department since then. New environmentalways brings unexpected difficulties, and great effort has given by me to getadapt to the new life. During the period of hard trying, both my knowledge andmy maturity have remarkably grown and I finally got rank above 12 % of 140, withoverall GPA 3.5/4.0, and major GPA 3.8/4.0. My hard working finally earned methe Outstanding Student Scholarship in 20xx.
Besides enhancement of knowledge in physics, I have also accumulated agreat 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 sciencecautiously.
My two years’ research in Structure Research Laboratory of USTC has broughtme to a more extensive and practical field of physics. Served as anundergraduate research assistant in Professor Xianhui Chen’s group, I havedevoted most of my time to the research and my knowledge in condensed matterphysics and its related fields have greatly increased. I have obtained all thebasic experimental skills in a very short time and in order to keep with thepace of the latest achievement in my research field, I have spent a large amountof 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 20xx, I began my systematical work in exploring thegrowing method and transport property investigations in hole-doped singlecrystal BSLCO (Bi2Sr2-xLaxCuO4+y) series and electron-doped NCCO(Nd2-xCexCuO4-y) series. My work was focused on the single crystal preparationand physical property measurement, especially the transport property andmagnetic properties. After so many times of attempt in the melting range anddescending speed, I successfully grew a great deal of single crystals with highquality. Moreover, I have spent so many days and nights together with mycolleagues in lab measuring the resistance of the single crystals under zerofield 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 stateproperty, I have submitted a paper titled “Field-induced log (1/T) divergingresistivity deviation from normal state in superconducting cuprates” to Phys.Rev. Lett. in 20xx as the third author. However, my work was not stopped andwith further investigation in the 2D weak localization system, I have submittedanother paper to Europhys. Lett. in October 20xx as a co-author.
Besides, through the work, I obtained almost all the skills of manipulationof 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 XRDpattern, 17 T Ultra-High Magnetic Field system (Oxford Science), AC AssistanceBridge (Liner Research Inc.) sputtering and so on. What’s more, I can skillfullyuse software, (GSAS, FullProf, CELL PCPDFWIN and etc), to analyze the structureof the material through X-ray diffraction data.
Beyond the achievement in research, the happiness I gained from thecooperation 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 makepeople gain their goals and the research work needs active and creativethinking. I often have discussion with other members in my group not only on thecurrent encountered problem but also on the some new ideas for research. Duringthe weekly group meeting, we often exchanged our views on our current researchproject and I have learned a lot through this communication.
Meanwhile, I never give up searching for more extensive and challengingfield. Actually, some of my present work is from my own idea. Known the misfitlayer of CoO2, I have grown some single crystals of highly efficientthermoelectric materials, such as Bi2Sr2Co2O, Bi2Sr2CoO6+y, Ca3Co4O9....... Inorder to find the relationship between the misfit structure of CoO2 layer andthe high thermoelectricity, magneto-resistance and magneto-power, I haveinvestigated the low-temperature transport, thermal and magnetic properties. Byreading a number of related papers, I plan to take further investigation ofthese materials through their thermoelectric potential and other relatedmeasurements.
With great interest in nano science, I have paid extra attention to thetechnique in synthesizing the nanowires and nanoparticles. Both from thecorresponding books in this field and experience of the PhD students in mygroup, I grasped a number of methods, such as micro-emulsion, hydrothermalmethod, sol-gel and other soft chemical ways to synthesize the nano scalematerials. Under the available condition, I am synthesizing the nano scalesuperconducting material YBCO and nanowires of magnetic materials, such asLa0.5Ba0.5MnO3.
More and more do I realize the importance of collaboration, during myexploring of the novel polycrystalline Co1212 and Fe1212. The samples werereported by some group to be superconducting only if it is annealed under theextreme pressure. I have measured the transport property of the crystals andobserved some abnormal phase transition of superconductivity. However, becauseof the limitation of experimental condition, our samples cannot becomesuperconducting. In order to solve the problem, we cooperated with Institute ofPhysics of China Academic Science to obtain the extreme pressure. Two papers ofmy work on Co1212 have been submitted to the international journals late thisyear, and I was the second author. In this case, I realized the cooperationwithin and without a group is equally important, and sometimes accomplishment isgained under several groups of people. We also have done some work in YBCO thinfilm transport property, collaborated with professor C. L. Chen ofSuperconducting Center Texas, U.S.A.
In addition, I have also attended some of other sub-group’s researchproject, such as using sol-gel method to grow Ru1212, NaCoO2 transport propertyinvestigation and colossal magneto resistance materials preparation. What’smore, I have also attended the 7th National Superconductivity Conference andNational Annual Conference of Physics in 20xx. My ken was greatly enlarged byhearing the report of the attendance and my confidence in my research wasincreased at the same time.
Research interest and future plan
Material of science and engineering is concerned with the study ofstructure, properties and applications of materials. During my two years’research in Structure Research Laboratory, I have accumulated plenty ofknowledge in the related area of material science, and meanwhile my ability indoing research is greatly proved. In the past work, I have done quite a lot insynthesis as well as characterization, and I have also deal with differentclasses of materials, such as electronic, magnetic, superconducting and so on. Ibelieve, aimed with strong foundation of physics, the appropriate area for me totake 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 recordingresearch, and I have great interest in this kind of materials. I believeresearch in this area is important both for basic studies of the effects ofdimensionality and interactions, and for the future of magnetic recording.Hence, I wish to do some work in synthesis and processing of this kind ofmaterials.
2. Because nano materials, such as carbon nanotubes, nano particles,quantum dots, nano-porous structures, and nano-electronics device materials, arethe essential part of the current and future nano-based technologies. I hopevery much to continue my future research work in this area.
3. Moreover, I am also interested in the structural material, such asadvanced engineering materials, which characters may be changed responding tothe different mechanic condition. So I think I also hope to do the relatedresearch in analysis of materials property.
My future plan is to pursue my PhD degree in material science andengineering. In fact, though the technology is developing at a tremendous speed,there is still a lot of progress remaining to be made. For instance, nanoscaledevices, either assembled lithographically or chemically, will have a highprobability of failure. Therefore, any architecture built from large numbers ofnano scale devices will necessarily contain a large number of defects, whichfluctuate 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 andcorresponding architectures. Such a framework can contribute towards buildingmore 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 theeconomic condition in California is not so satisfying at the moment, I believeit will not impede the future development of UCSD.
The Materials Science and Engineering Program at UCSD aims to providefundamental knowledge for understanding of materials with the objective ofpredicting, modifying, and tailoring the properties of materials to yield, atthe technology level, enhanced material performance. Also, I was greatlyimpressed by the great collaboration of different departments, which makes theMaterials Science department more competitive and attractive. With so manyoutstanding professors and so broad research areas, I was convinced that theMaterial Science and Engineering Department is always the best choice for me topursue my PhD degree.
Yours sincerely,
