Hyperscripts of AMAT: General Information

(As of: 31 January 2023)

Important: Make sure to avoid seeing an old, cached version of this page (or any other page of the script) by forcing to refresh this frame's content.

Recent Information

Here (at the top of this page) all recent information will appear.
  {short description of image} From the second week on, we will reverse the order of exercise and lecture, and we will start one hour earlier, i.e. we will have the exercise from 13:15 until 14:00 and the lecture from 14:15 until 15:45 (no change). This way, we will use the exercise to review the contents of the previous lecture.
  {short description of image} In addition, exercise and lecture will take place in a hybrid mode, i.e. both in the lecture hall and online via BigBlueButton (https://mediaportal01.rz.uni-kiel.de/b/j-m-kix-xnk-9tj). There, you can also have a look at recorded lectures from previous years. Please write me an e-mail (jwa@tf.uni-kiel.de) to obtain the access code.

General Information

All general information will appear here; last update: 13 October 2022.
  {short description of image} You may encouter errors in the script, especially in the modules not belonging to the "backbone" (cf. the "Matrix of Modules"), but also in the backbone itself. My recent corrections are not yet included in the PDF version of the script. In any case, if you are in doubt about the correctness of some module, or if you have found an error, tell me about it by e-mail: jwa@tf.uni-kiel.de.
  {short description of image} To be able to follow this lecture, basic knowledge on the quantum-mechanical level about solid state physics (i.e., that electrons can be described by wave functions) and light–matter interaction (i.e., that light comes and goes in photons) is required. (You see? Classically, matter consists of particles, while light is a wave. Quantum-mechanically, however, it is the other way round! Or is it?)
  {short description of image} We will focus on selected parts of this script:
  • Chapter 2, Basic Semiconductor Physics: Basic Band Theory; Basic Semiconductor Physics; Elements of Advanced Theory
  • Chapter 5, Fundamentals of Optoelectronics: Materials and Radiative Recombination; Light and Semiconductors; Heterojunctions; Quantum Devices
  • Chapter 6, Principles of the Semiconductor Laser: Laser Conditions
  • Chapter 7, Light Emitting Devices: Basic Requirements and Design Principles
The reason for this choice of chapters lies in the main goal of this one-semester course: to provide a good understanding of the basics of semiconductors and of optolectronic devices, serving as a starting point for the participants to be able to get deeper into the matter at some later time, if required by circumstances.
  {short description of image} There is a list of books related to this lecture course, providing both German and English titles (scroll down for the latter ones). This list also includes an online book (in English). Besides the various headlines of the present script, the subjects treated in the exercises may serve as a guideline for what to read in those books.

Exercise Task Sheets

The following table contains the question sheets; they will be discussed at the indicated date.
  {short description of image} An active participation in the discussions, including some work at the blackboard, is a required prerequisite for taking the oral exam.
  {short description of image} Please tell me (jwa@tf.uni-kiel.de) if you encounter technical difficulties with the PDF files, or if you prefer a different file type (as, e.g., XPS or TIFF).
