This video is part of the nanoHUB-U course "Thermoelectricity: From Atoms to Systems." The third-fifth week is taught by Ali Shakouri. (http://nanohub.org/courses/teas)

This five-week short course introduces students to the thermoelectric theory and applications using a unique, "bottom up" approach to carrier transport that has emerged from research on molecular and nanoscale electronics.
The first two weeks of the course introduce this new perspective and connects it to the traditional treatment of thermoelectric science. Landauer formalism provides a unified framework to study both electron and phonon transport. The following three weeks introduce latest nanoscale and macroscale characterization techniques, the design of thermoelectric systems, and recent advances in nanoengineered thermoelectric materials and physics.
