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
global challenges in the academic fields of nanoelectronics, material and device characterization
as well as display technology. As I pursue my goal as a prominent scientist or engineer, I require
many attributes: enthusiasm for learning various subjects, immense aspiration to solve emerging
problems,  and  fierce  dedication  to  research  in  particular  fields.  Accordingly,  I  possess  these
qualities and  will  showcase  them  in  your  program  at  Department  of XXX, XXX University.

In  retrospect,  my  college  education  greatly  facilitated  my  natural  attraction  to  research  in
material properties 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  some
impressive contributions. Specifically, my main research are related to  single-molecule magnet
and organic semiconductor.

First, my most intensive contributions to computation involve the discovery of a new method to
calculate  the  exchange  coupling  constants  in  a  single-molecule  magnet  in  2013.  Likewise,  I
published a  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 spin orientation configurations and solve liner equations.  However,  when  this  method  applies  to  molecules  containing  large  number  of
magnetic atoms, it becomes extremely cumbersome. In paper with XXX(Prof. name) appearing in the XXX(journal name), we proposed a new method based on first-principle calculations. To illustrate, we reversed the spin  orientation  of  the  two  atoms  respectively  and  spontaneously;  the  calculation  results  were consistent with previous researches 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 electronic and magnetic properties of an organic semiconductor. In this paper, the magnetic properties and electronic structure of 3d transition-metal phthalocyanine doped with 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  success fully articulate the magnetic moment causes and level arrangement law.

Based on my eminent research successes, my motivation flourished. There are many interesting,
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 an interesting topic. I have always been interested in fabrication process and design and want to  do  intensive research  on  improving  process technologies  to  ameliorate performances of the device such as HFET.  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 is far from
complete if one does  not also find a way to clearly present it to others. Even more importantly,
organizing a vast array of results for a presentation is a crucial skill that a researcher must share
with a teacher: without it, the researcher cannot gain a clear sense of direction in his work. My
interest in teaching emerged two years ago when I tutored a high school student. It was a great
pleasure to teach students, especially probing students’ minds to judge difficulty based on 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 to continuing my research career as a PhD student. The aforesaid open problems deeply motivate me, and I will continue to pursue these topics. Your department occupies a forefront position in the solid-state electronics and materials field, especially  in  the area of Liquid Crystal Display. Students and professors publish valuable papers in top conferences and journals yearly, and most of their research encompasses a close relationship with the industrial community. My investigation  of  your  program  revealed  an  honorable academic  community,  state-of-the-art technology facilities and stimulating research atmosphere, all of which are highly conductive to
the development of my later academic career. As Socrates proclaimed, “The unexami ned life is
not worth living.”

Thus, I am eager to examine innovative research and content in your amazing setting!

Sincerely yours,
XXX
