Electrons in Low Dimensional Systems 
Summer semester 2021
Chair of Experimental Physics (E20) - (Prof. Barth)
(Contact information)
Allocations: 1 
Angaben zur Abhaltung
(1) Free and confined electrons in solids.
(2) Electrons in a periodic potential: band theory of solids and dimensionality. Semiconductor materials, graphene and carbon nanotubes.
(3) Two-dimensional electron gas. Quantum wells, quantum wires, quantum dots.
(4) Surface electronic states, surface confinement, density of states vs. dimensionality.
(5) Nanostructures and 2-D materials: from top-down control to bottom-up assembly.
(6) Some important experimental techniques (scanning tunneling microscopy and spectroscopy, angle-resolved photoelectron spectroscopy, two-photon photoemission, inverse photoemission etc.)
(7) Tunneling and tunnel junctions.
(8) Coulomb blockade and single electron transistors.
(9) Classical and semiclassical transport, ballistic transport, quantum resistance.
(10) Quantum Hall effect and topological states.
No preconditions in addition to the requirements for the Master’s program in Physics.
After successful completion of the module the students are able to:
(1) understand the physical laws governing the behaviour of electrons in solids and the influence of the reduced dimensionality;
(2) understand the role of nanoscale phenomena and electron confinement in determining the electronic properties and physical behaviour of nanostructures;
(3) evaluate the potential for exploitation of confinement effects in devices and applications.
