12/8 Just one comment for the paper page limit of a manuscript. In the classroom, professors would accept a work beyond the page limit because contents are more important. But if you submit to a professional journal, you want to be extra careful. Many journals will reject your submission without any technical review, especially if they provide a template (e.g., EDL). Even without a template (e.g., APL and PRL), authors must estimate the number of final pages in advance. The Editorial Office explicitly asks referees to warn authors regarding the number of pages whenever they sense any potential problem. This has nothing to do with science, but if you face automatic rejection due to the page limit, you eventually have to find another journal... -TY

12/7 I have received everybody's term-paper in time. I am happy with your hard work, and hope you have enjoyed the experience of conference presentation and paper writing. After writing a paper, you have to "fight" with referees. This is where you have to sweat a lot. Some of them are reasonable, and some are not. In the future, I want to give you some guidance for it. BTW, I will teach EE232 Quantum Electronics in Spring 2016, so if you are interested, see you there. Have a nice break. -TY

12/6 This is a friendly reminder that the term-paper is due at 10 pm tomorrow, 12/7 (Mon). I have some advice. Cheers, -TY

  • Please use feedback at the oral Q & A session effectively.
  • Please follow the designated EDL format, up to 3 pages.
  • Don't forget references especially when you drop some topics due to page restrictions.
  • Don't forget to write introduction, main text, and conclusion.
  • Don't forget to write captions below figures.

12/5 The term-paper deadline is at 10 pm, 12/7 (Mon). -TY

12/2 Everybody is suffering between time restriction of 10 min and more topics to cover. Practically, you need to drop some topics. Here, you can cite references. Because audience is an ensemble of well-educated scientists, by giving references, they should be able to catch up with you immediately. -TY

12/1 I have received everybody's submission in time. Now you have an option to revise your slides if you want, by 10 pm tomorrow, 12/2 (Wed). Here are general comments. You want to cite a reference on the page where you cite somebody's work (plot). The reason is obvious. In a conference, if you see your own plot (you may have spent a week in a lab without sleeping on the bed...), and what if the presenter doesn't show your name timely... Audience will assume the presenter him/herself successfully took the data in the very difficult experiment... You may feel disturbed, and may start saying that the presenter "stole" my data. This is a presenter's nightmare because he/she doesn't necessarily have any evil will, simply doesn't know the rule in the science community. But the presenter is to be blamed. Some people list all references at the end, but because we want to prevent this troubled situation, I strongly recommend you to cite at the page where you show somebody's data. In fact, if you read very old Phys Rev papers, you will find references are listed on the same page as footnotes. See you on 12/3 (Thu). -TY

12/1 You can assume well-educated intelligent scientists as audience. By citing references, you can save time/pages for discussing fundamentals in textbook-type background and concentrate on the key topics more, such as latest-paper-like background. -TY

12/1 I started receiving submissions. My feedback so far is related to the number of pages or topics. You want to aim at a 10 min talk. That's a game to select a few key topics rather tahn pack as many topics as possible. Which topics are more essentail than the others? Would your presentation be more effective if droping topics C-G and concentrating on topics A and B? -TY

11/29 Oral presentation program posted. There are something you need to know about conference presentation in genereal, so please check the footnotes. -TY

11/28 There was a question for presentation and term-paper. Which is expected, (1) proposing a new project or (2) reviewing existing works? Either one is fine. But even if you want to propose a new project, you need to "position" it, meaning you need to analyze existing works, and discuss how your new project fits into the present status of our science community. So reviewing existing works is necessary in both cases. I generally expect (2), but if you want, you can add components of (1) in your presentation (in fact, there is "proposal writing" and you could add some flavor). -TY

11/27 I think you are busy in preparing slides. It is critical to understand key papers. Even if you cannot derive all mathematics or understand all experimental details (if you can, of course that's great), you absolutely want to understand the logical flow in the papers. That's what you want to present in your talk. Also, please consider an effective use of "however". -TY

11/25 Slides due at 10 pm, 12/1 (Tue). Oral presentation on 12/3 (Thu), term-paper due on 12/7 (Mon). As discussed in class, you need to have high brain pressure before preparing slides or a term-paper. Read relevant papers and consider deeply. -TY

11/20 Class schedule, 11/24 = lecture, 11/26 = Thanksgiving, 12/1 = last lecture & slides due, 12/3 = oral presentation, 12/7 = term-paper due. The last term-paper due is to be finalized and is a little flexible. If you have any schedule conflict, please let me know. -TY

11/19 Tunneling devices discussed. They are old and new. As a new side, tunneling FinFET is hot now, while resonant tunneling diode or Esaki diode are classical in the literature. -TY

11/18 Those who are given many comments, suggestions for revision could re-submit a revised abstract (there is no specific deadline). Grading leading to A, B, ..., will be done for the presentation and term paper, but historically, there is a strong correlation between the abstract and presentation/paper. For writing a good abstract, you need to read relevant papers and consider/analyze deeply. Thus, having a good blue print now is highly beneficial for your presentation/paper in December. -TY

11/18 The oral presentation is planned on 12/3 (Thu) and you must be in the classroom. If you have any schedule conflict, please let me know immediately. Otherwise, this is an oral presentation day. The power point slides are due on 12/1 (Tue), and the term paper is temporary due on 12/7 (Mon). These dates will be finalized. If you have any schedule preference, please let me know. Regarding the presentation and term paper, you need to read papers and consider things, so that you have many things to say. If you start preparation before reaching this state, it is extremely difficult to create slides and write a term paper. Enough preparation in advance is important. This applies to real conference presentation and journal paper writing, too. -TY

11/18 The graded midterm returned. The full score is 198 and the median is 128. The solution is uploaded, so please review using it. Many people had trouble with the Bloch, and the last problems. In the Bloch, you just need to be familar with plotting a complex function. In the last problem, the second-order differentiation of energy with respect to momentum is 1/m, which will influence the mobility and state density. -TY

11/17 Abstract comments sent individually. The midterm sol posted. -TY

11/12 Advice for abstract writing: In the abstract, you need to spend ~1/3 to ~1/2 of space for a general introduction. Why? Science now is highly developed and (ultra)specialized. it is practically impossible for anybody to keep track of all topics. Therefore, don't start a microscopic, detailed, ultraspecific discussion in line 1 before giving a general idea to readers. If you want to see examples, you can just search over the Internet. -TY

11/12 Please start preparing an abstract. You can download the template, and simply replace the title, author, text, and references. This is a version truly used for the MRS meeting. One page, no figure format is quite typical. The conference committee will decide talk/poster based on your abstract. In the worst case, they say this abstract is not within the scope of the conference and is rejected, which will be the last thing you would like to face, so you really want to give your best short. The deadline is at 10 pm, 11/16 (Mon). -TY

11/10 Good news. I have received everybody's midterm in time. I want to ask you a favor. If you turned in multiple pages, please combine them into a single file. I will print out everybody's midterm and start grading, so if you can provide me a unified single file, that's very helpful. 11/12 Updates: Thank you, all. I have a single file version of everybody's midterm now. -TY

11/10 Urgent comment regarding the midterm: please combine your answer sheets to a single file and send it to me. If there is any file (computer engineering) problem in your submission, I will contact you individually. -TY

11/10 This is a friendly reminder that today 10 pm is the midterm deadline. Please combine your answer sheets into a single file and send it to me via email. In today's class, I will go over the abstract, oral, and term paper. Please try to attend. -TY We have discussed the Hall effect extensively. -TY

11/9 Lectures are video-taped and posted here. Please check it. There is a second page, please click page 2 at the right bottom of the page, if what you are looking for is not at page 1. -TY

11/8 Week 7 note posted. -TY

11/6 The midterm exam has been distributed via email. The deadline is 11/10 (Tue) 10 pm. Late submission penalty is 10 % per hour. Please use this opportunity to review technical contents we have discussed in class so far. Good luck. If you don't receive anything, let me know immediately.  -TY

11/5 Tomorrow the midterm will be distributed via email. I expect sometime in the afternoon. Today, we discussed the temperature dependence of a Fermi level in semiconductors, which is very diffdrent from that in metals. -TY

11/4 HW5 sol posted. There is no need to submit HW6 (sol also posted), because we will have the midterm. Template files are posted for final presentations. Please start preparation well in advance. I will let you know important deadlines later. The abnstract is due on 11/16 (Mon) as discussed below. -TY

11/3 Midterm (take-home) distribution on 11/6 (Fri) and submission on 11/10 (Tue). Details will be announced soon. Abstract (within a page, the title , name, and sbstract text must be written) submission by 11/16 (Mon). -TY

11/2 Week 6 note uploaded. -TY

10/30 Lectures are video-taped and posted here. Please check it. -TY

10/29 We discussed DOS in various dimensions. Then the Fermi-Dirac function is introduced, which minimizes the Helmholtz free energy pursuing minimizing internal energy and maximizing entropy the same time. -TY

10/28 As I briefly discussed in class, the mode matching technique we used for 1D atomic array analysis is not a practical method, and unfortunately, nobody uses it now. The biggest problem is that it is not feasible to extend it to 3D. The tight-binding method, based on the Bloch sum, is one of the most popular techniques now, enabling realistic 3D modeling. If you are interested in modeling/theory, this is a very good final presentation topic. -TY

10/28 HW4 sol and HW5 posted. -TY

10/27 Valence band electrons and holes are discussed. -TY

10/25 Week 5 note uploaded. -TY

10/22 1D periodic QW and 3D E-k relation discussed. The midterm is temporary scheduled as follows: distribution on 11/5 and submission on 11/10. If you feel comfortable with HWs, you will have no problem. If you are a little behind the class schedule, use this midterm exam for catch-up and review. After midterm, we are moving to state-of-the-art materials and devices. If you have any personal schedule conflict, please contact me. -TY

10/20 If you want to major in modeling/theory, the present level of math is mandatory. You want to be able to derive all equations. If you want to emphasize experiments, you should be able to state the starting equations/assumptions. The conclusion is often shown graphically, and you want to understand what it means. -TY

10/20 If you are looking for a finial presentation topic, you can check "EE227 syllabus2 further references." Papers are discussed, and you can choose your topic from there. -TY 

10/20 Enegy bands and band gaps discussed. HW4 posted. HWs will be assigned on Tue, and due on the next Tue, unless directed. 227_ref_detailed_calculations posted. This is my note for a lecture I gave at a different institution. The same topics are copnvered, and all calculations are shown in detail, including today's band calculations. -TY

10/15 1D finite QW discussed. -TY

10/14 HW2 sol and HW3 posted. -TY

10/13 We have examined a 1D finite potential well. -TY

10/9 We covered basic quantum, Schrodinger, discrete k and E, eigenstates, Heisenberg, parity, etc., in the context of 1D quantum well (QW). -TY

10/6 HW2 posted, due on 10/13. People with late registration may submit HW1 a little late, but please keep the regular schedule from HW2. -TY

10/1 Today, we studied lattice & basis, and zincblende and diamond. This happened to a few students before and I just want to mention it. Depending on your (lab) schedule, you sometimes have to work at NASA and sometimes at UCSC. There is no problem in switching a classroom, e.g., registering for 01 and attending a class 50 (or vice versa) is totally acceptable. Just choose a closer classroom for your convenience. No tedious paperwork necessary. Just come to a classroom of your choice. -TY

9/29 Lectures are video-taped and posted here. Please check it. -TY

9/29 If you don't see attachments, please log in using your blue Cruz ID. -TY

9/26 HW1 posted, due on 10/6 (Tue). A small change for grading weight, HW + quiz = 10 %, midterm = 30 %, and final presen = 60 % (weight scheme w1). I may also use a different weight scheme (say, w2) and your score will be max(w1,w2). -TY

9/25 By now, you should be able to see this announcement and uploaded files. If you have any toruble, please let me know. -TY 

9/24 We talked about electrostatic capacitance and quantum capacitance. Sylabus files are posted below. -TY
