# Recent Information

| Here (at the top of this page) all recent information will appear.
|  | For those who have registered to take the oral exam within the next weeks: Just send me an e-mail (jwa@tf.uni-kiel.de) to suggest two dates for the exam that suit you. After checking with my co-examiner I will reply to you.
|  | The lectures of 21 Dec. 2021 as well as of 11, 18, 25 Jan. and 01 Feb. 2022 have been recorded in BigBlueButton and are ready for viewing/downloading (roughly 321, 407, 336, 302, and 245 MB, respectively).
|  | The YouTube video that I referred to in the last lecture was mentioned only beforehand in the exercise: www.youtube.com/watch?v=S1A_Gx3F2CI ("So schneiden Laser Metall | DieMaus"; if necessary, you can activate automatically translated English subtitles), with the part most relevant for us starting from 3:20. Thanks a lot, Jannik Rank, for pointing it out!

# General Information

| All general information will appear here; last update: 30 November 2021.
|  | 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.
|  | To be able to follow this lecture, basic knowledge on the quantum-mechanical level about solid state physics and light–matter interaction is required.
|  | 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.
|  | 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.
|  | An active participation in the discussions, including some work at the "blackboard" (i.e., its online equivalent), is a required prerequisite for taking the oral exam.
|  | 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).
