# Semiconductor, Quantum transport and Fermions ## Semiconductor nanostructures The following contents are notes of the courses [402-0595-00L  Semiconductor Nanostructures](https://www.vvz.ethz.ch/Vorlesungsverzeichnis/lerneinheit.view?lerneinheitId=162031&semkez=2022W&lang=en) by Prof. Dr. Thomas Markus Ihn. The reference book is [[Semiconductor Nanostructures]] ([online version](https://academic.oup.com/book/9679)). The contents cover from basic semiconductor theories to 2DEGs and experiments setups for quantum experiments (mainly Fermions), phenomena and topics like Aharonov-Bohm effect, Shubnikov-de Haas effect and quantum Hall effect are also covered. In the future, topological (insulator) related contents will also be added here. On this page, all main topics will be listed. 1. [[What is a semiconductor]] 2. [[Semiconductor crystals]] 3.
