General Information

Main field: Nanoscience.
Compulsory for: N4-nf
Elective for: E4, F4, F4-nf, N5-hn
Language of instruction: The course will be given in English


This course concerns artificial materials with substructure on the nanometer scale such that the electronic motion is restricted to two, one or zero dimensions. The emphasis is on semiconductor heterostructures but also other low-dimensional systems will be discussed. The concepts and the underlying theory are introduced based on quantum mechanics and extended by the application to heterostructures. After the lecture part of the course is completed, the student will work on a project within a research group for about 1,5 weeks. The project work will be presented orally as well as in writing.
