I have clearly defined my career goal to become a well -rounded and technically competent specialist in Materials and Devices, effectively utilizing innovative technologies to address globalchallenges in the academic fields of nanoelectronics, material and devicecharacterization aswell as display technology. As I pursue my goal as a prominent scientist orengineer, I require manyattributes: enthusiasm for learning various subjects, immense aspiration tosolve emerging problems, and fierce dedication to research in particular fields. Accordingly, I possess these qualitiesand will showcase them in your program at Department of XXX, XXXUniversity. In retrospect, my college education greatly facilitated my natural attraction to research in materialproperties and applications. I have been working in this area for two years, under the supervision of Professor XXX. During this challenging time, I have achieved someimpressivecontributions. Specifically, my main research are related to single-molecule magnet andorganic semiconductor. First,my most intensive contributions to computation involve the discovery of a newmethod to calculate the exchange coupling constants in a single-molecule magnet in 2013. Likewise, I publisheda paper--(paper title)--in the Journal of XXX in Aug. 2013. In the study of material properties of a single-molecule magnet, we need to calculate the exchange coupling constants frequently. We initially choose different spinorientation configurations and solve liner equations. However, when this method applies to molecules containing large number of magneticatoms, it becomes extremely cumbersome. In paper with XXX(Prof. name) appearingin the XXX(journal name), we proposed a new method based on first-principlecalculations. To illustrate, we reversed the spin orientation of the two atoms respectively and spontaneously; the calculation results were consistent with previousresearches on similar molecules. After the study of a single-molecule magnet, I thoroughly investigated the properties of other materials and recognized my instinctive patterns of reasoning as highly analytical. One of my submitted papers--XXX(paper title)--in Jul. 2014,concerns the electronicand magnetic properties of an organic semiconductor. In this paper, the magneticproperties and electronic structure of 3d transition-metal phthalocyanine dopedwith Li were calculated utilizing first-principles calculations based on density functional theory. However, we discovered that different types of phthalocyanine have different electronic structures;in essence, they do not follow certain obvious rules. In my joint work with XXX(Prof. name) and other teammates, we bravely employed the orbit mixing and splitting theory to successfully articulate the magnetic moment causes and level arrangement law. Basedon my eminent research successes, my motivation flourished. There are manyinteresting, open problems relating to material properties that I intend to investigate. Perhaps the most intriguing one is exploring new materials with high performance, which is one of the main factors restricting the development of materials and devices. For example, using III-IV compound semiconductors to design transistors is becoming a new research hotspot. Besides, device processing is also aninteresting topic. I have always been interested in fabrication process and design and want to do intensive research on improving processtechnologies to ameliorate performances of the device such asHFET. In turn, I would like to approach these problems--exploring material properties and finding their functions--through my future study in your program of PhD in XXX (department name). Similarly,I strongly deem teaching as an integral part of doing research. A discovery isfar from completeif one does not also find a way toclearly present it to others. Even more importantly, organizinga vast array of results for a presentation is a crucial skill that a researchermust share witha teacher: without it, the researcher cannot gain a clear sense of direction inhis work. My interestin teaching emerged two years ago when I tutored a high school student. It wasa great pleasureto teach students, especially probing students’ minds to judge difficulty basedon their abilities. Now I aspire to become a university faculty member to perform research as well as teaching. In essence, I choose (university name), as it emphasizes the nurturing our students to become well-rounded and technically competent engineers who can change the world. I passionately look forward tocontinuing my research career as a PhD student. The aforesaid open problemsdeeply motivate me, and I will continue to pursue these topics. Your departmentoccupies a forefront position in the solid-state electronics and materialsfield, especially in the area of Liquid Crystal Display. Students and professors publish valuable papers in top conferences and journals yearly, andmost of their research encompasses a close relationship with the industrialcommunity. My investigation of your program revealed an honorable academic community, state-of-the-art technology facilities and stimulating researchatmosphere, all of which are highly conductive tothedevelopment of my later academic career. As Socrates proclaimed, “The unexamined life is notworth living.” Thus,I am eager to examine innovative research and content in your amazing setting! Sincerelyyours,
