When China, my motherland, is mentioned anywhere in the world, people will naturally awaken association with the exquisite and beautiful chinaware made in China, the country that enjoys a history of porcelain production one thousand years earlier than other countries and a reputation for her elevated art and remarkable craftsmanship. European people attempted at any cost to acquire the technology of porcelain making and at last achieved the satisfaction of this goal from a priest named Francois-Xavier D’Entrecolles, thus the present variety and brilliance of chinaware in both China and the West. Nevertheless, in an era of electronics and information today, China has fell far behind the advanced countries in the field of information materials science and engineering, in its research and application as well. As a graduate majored in physics and technology of electronic thin films, I am eager to trace the footprints of Francois-Xavier D’Entrecolles so as to bring the advanced technology of material engineering to China by means of studying in your prestigious university for Ph.D. program in the area of material engineering, realizing my dream of being a useful scholar to my motherland.
University of XX is a world-famous university and especially well-known for her intellectual strength in the area of material engineering with her irresistible magnetic power pulling excellent students from all over the world to her. Therefore I justify clear realization of the sharp competition I am confronted with. But with a fine background of education in specialty, a firm foundation in theoretical study, the practical skill in experiment, and the cultured ability to engage myself in independent research work, I have the confidence to meet the challenge from other rival applicants.
In University of XX of China, which enrolls brilliant students from various areas in China with her strength in the area of material science, I accomplished my undergraduate study in the specialty of magnetic materials and components and my graduate study in physics and technology of electronic thin films, in the period of which I kept to be the top student in my class and was awarded the school fellowship every year. I was elected “Graduate with Merit” of my university upon graduation.
Benefiting from the strict training in my university, I gained fair acquaintance with the knowledge and theories in my specialty. Meanwhile, I read various journals and magazines at home and abroad, following the footsteps of the development of new theories and technology. I tried my best to participate in possible experimental work and research work, cultivate my skills in the use, maintenance, and modification of vacuum-evaporation equipment and pulse-laser- deposition equipment, and attend academic workshops and symposiums. The modulation rate of the BST voltage controlled thin film variable capacitor I produced reaches the level of 80%, approximate to the highest level in record so far.
My achievement was highly appreciated by relevant scholars and specialists and I have been invited to participate in various programs experiments. As a result of my persistent effort, I have published “BST Voltage Controlled Microwave Electronic Components” and “STO Pulse-Laser-Deposition Growth of Thin Film” respectively on such kernel academic journals as XX in China, the former article being praised by relevant specialists as “assuming the function of guidance to the application research on BST thin film in China.”
Based upon the confidence of my theoretical background and research capacity, I chose the topic “Production of High-frequency Composite” for my Bachelor’s thesis. On the basis of extensive collection and absorbing of the recent information on magnetic materials and components, I decided to do my research on the project of compounding Co2Z material by applying Y2O3 and Sr2+ and adopting pre-processing technology, in addition to the control of working procedure and temperature point. In consequence, the improvement of magnetic property of the material. In the oral defense of my thesis, the present specialists concluded that the research, measuring high academic significance, was novel in topic selection, logical in argument, and creative in idea. My Bachelor’s thesis was chosen as “Excellent Thesis” of the university through critical assessment.
At present, I am busy with my Master’s thesis “Au/BST/YBCO Ferro-electro Thin Film Voltage Controlled Components.” There exists a great difference between China and Western countries in experimental conditions with regard to BST thin film materials and we cannot produce desirable microwave components with available references nowadays. But the RMS on the surface of the BST thin film I designed and produced is of merely several angstroms , the modulation rate 80%, and the power loss 4‰, which satisfies the need of microwave component production. This achievement is at forefront in China at present.
During this period of study and research, I have deeply felt that my country falls far behind the advanced countries in the area of materials science and an intense need to study the advanced theories and technology in the fullest enforced academic institute. Thus I select_ University of XX where I believe I can realize my dream. In addition to the unparalleled strength in the area of materials science and technology, University of XX boasts the international background with scholars and students from different regions all over the world, the congenial atmosphere of academic research, and the systematic cultivation of creativity in her students. I am eager to enjoy an opportunity to enrich myself from this valuable academic nutrition and at the same time I hope, on the premise of the improvement of my theoretical construction and of my experimental capacity, to give full play to my initiative and potential strength and in this way to contribute my intelligence to University of XX -+in the participation in relevant research projects.
