The aim of this course is to give doctoral students a background relevant to research in the physics of low dimensional structures and quantum devices. The course aims to give the doctoral student knowledge so that the student can formulate and solve problems in his or her research. 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.

Undervisningsformer: Föreläsningar, laborationer, övningar, projekt
Examinationsformer: Skriftlig tentamen, skriftlig rapport, seminarieföredrag av deltagarna.
Assessment: Written exam and home assignments. Graded laboratory exercises and project work. The final grade is based on a weighted average of the grades on the laboratory work (25%), the project work (25%) and the written exam (50%).
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
