Could you help me for correct my errors, and I want to make my SOP shorter.
I've tried to, but it seems still to long...
thanks a lot!

I decide to pursue my Master of Science degree in electrical and computer engineering (ECE), and I wish to further my study to a PhD program with an emphasis in solid state physics and devices, optoelectronic devices, and photonic crystals. "General", with great reputation of providing distinguished professional trainings and rigorous research activities and resources, is my ultimate decision.
There are several important classes I took during undergraduate stimulated my desire for graduate studying. As in a chronological order, the first class inspired me should be Semiconductor Device Physics. In this class, I started to realize how semiconductors are fabricated, how they work as electronic devices, and the theories behind those amazing structures. I also took Introduction to Quantum Mechanics and Modern Physics to gain essential knowledge about electrons, photons, and semiconductors. I found myself aspiring to know more about the theories related to semiconductors and its applications. Thus, right after that semester, I took Introduction to Quantum Mechanics (II) and I started working on a National Science Council college student research project. This project gives me the greatest impact and is the most important event during my whole undergraduate life. A thorough description about my project will be provided in the next paragraph. Back to our topic, during my junior year, I almost finished every undergrad level course available in NCTU about solid state devices and physics. I had excellent performances in every course mentioned above (all got A while represent in letter grade); however, this is far from satisfying my desire for comprehensive and depth learning. Without any hesitance, I decide to give myself some challenges during my senior year --- I took 7 graduate level classes in my last year as an undergraduate student. Fully motivated, I had been studying thoroughly and diligently on each course. As a result, I not only advanced significantly but also got outstanding grades in several classes. For instance, I was ranked 2nd place in graduate level Quantum Mechanics among whole class and the grade is 92 out of 100. To sum up, I spent most of my time during undergraduate making myself well-prepared and competitive for graduate study and research.
I have established a solid sense of research through my NSC's College Student Research Project. I met Prof. Lee, who is my advisor of the project, in her modern physics class. Her areas of interests are photonic crystals and solar cells. I found that photonic crystal is an interesting and suitable research topic for me since my interests mainly focus on optoelectronic devices. At beginning, I don't even know the detailed theories behind photonic crystals, so I have to study intensively and diligently to start my research. I read Dr. Joannopoulus' text book first, then I study as many papers as possible to extent my knowledge about the research. About a month later, I constructed a sound structure for my research, and I determined my topic to be the enhancement of photon conversion efficiency. I discovered that by utilizing the band-edge mode of graphite lattice of photonic crystals, which photons travel at relatively low speed, I can prolong the interaction time between photons and the quantum wells on the substrates. In this sense, more photons can be converted into electrons through this mechanism. The experiment shows that Photoluminescence(PL) is enhanced 8-10 times on our devices in compare with bare substrate without photonic crystal patterns. Also a red-shift on spectrum is observed when we change the r/a value of our crystal patterns; this further proves that the enhancement is caused by our design of photonic crystals. I also gained many skills of doing simulation and running a fabrication process of the device. I learned how to use auto-cad to draw the patterns I want to design, and I learned how to use RSoft's simulation to examine if the design works out correctly. I also learned how to operate an e-beam lithography system to make a real device. To conduct experiments to verify our thoughts, I learned how to construct a Near-Infrared Micro-Photoluminescence system to make observation of real devices. To sum up, in this project I have learned a complete set of knowledge and skills to accomplish a research about photonic crystals.
To become a competitive graduate student and researcher, I not only have outstanding academic performance within solid state field, but also have a solid research foundation. What make me even more ready and competitive are my working experiences. After graduate from NCTU, I decide to stay one year working as a full time laboratory assistant. My responsibility is to teach undergrad students to do experiments of microelectronic circuits such as multistage amplifier of MOS and BJT. I have been assigned to teach an English class, so I have to prepare all the slides, give lecture, and guide students doing experiments in English. The experience of instructing foreign students sharpens my ability to teach and learn things well in English and makes me more compatible for T.A jobs in my PhD life. The reason I chose this job is that working in NCTU could benefit me in several ways. For example, as I work in electrical engineering department, I have the chance to get involved in research opportunity even after I was graduated. I participate in Prof. Steve Chung's lab as a part-time researcher. I have learned how to analyze the reliability of CMOS devices. I also start my own research project of a study of the variation of threshold voltage caused by effect of random dopant fluctuations (RDF). Even after graduated and started working, my training of doing research never stops.
As I learn more, my desire to make progress is stronger. I would very much like to pursue my goal at a top university where I am allowed to work more effectively and creatively. "General" is my dreaming choice, and I wish that I could have an opportunity to achieve my academic goal with "General" .
