In this course we focus on low-dimensional systems with typical length scales in the range of 1-100 nm. At this small length scale quantum mechanical phenomena play a dominant role in the physics of devices. Prominent topics are quantum electronic transport, both coherent and incoherent, Coulomb blockade, and the quantum Hall effect. The physical description of these phenomena is illustrated by examples from current research in nanophysics. Often we revise, exchange or add new timely topics to this course. During the last few years we have added the following topics: graphene, 2D Dirac materials, moiré materials/twisted materials and quantum spin Hall effect.
Assessment
Throughout the course the students will have to solve three homework assignments. These homework assignments will be marked. The results of the homework assignments count for 1/3.
At the end of the course there is a written exam of 3 hours. The exam is an open-book exam. The mark of this written counts for 2/3.
