Aims

Introduction to the electrical and thermal conductivity of materials by emphasizing the physical mechanism at the This lecture provides a description of the main electrical and thermal transport phenomena in materials. It also gives an introduction to the specific transport properties in nanostructures and low dimensional systems, including quantum effects. Finally, the students become acquainted with experimental set-up used for transport measurements.

Main themes

The covered topics include : electrical and thermal conductivities, thermoelectricity, experimental aspects, effects of temperature and magnetic field, spin polarized transport, electrical transport in two-dimensional and one-dimensional systems and molecular transport.
