Content

Modern techniques allow the fabrication of structures and devices in the range of nanometers, such as semiconductor quantum dots, atomic wires or single-molecule contacts. In these systems, the mean free path of electrons is often significantly smaller than the dimension of the structure. As a result, charge and heat transport properties differ significantly from that of macroscopic systems. Quantum mechanical tunneling processes and interference effects influence the transport properties and phenomena such as ballistic transport, conductance quantization or Coulomb blockade are observed.
This lecture course introduces theoretical concepts and methods used to describe quantum transport in nanosystems. After an introduction into the topic and a brief recapitulation of macroscopic transport theories, we first discuss Landauer theory, which describes transport as a scattering problem. Then advanced methods for transport in interacting systems will be discussed. The theoretical methods are applied to analyze physical mechanisms and transport phenomena in nanostructures.
