This video is part of the nanoHUB-U course "Thermoelectricity: From Atoms to Systems." The first week is taught by Supriyo Datta. (nanohub.org/cou...)
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.

Sorry if this is a basic question, but at 7:30 you talk about electrons going in and electrons going out. Is that because n-type materials have extra electrons and p-type materials have electrons holes? If so, is that center rectangle essentially made up of a series of n-type & p-type materials?

It seems like larger the difference between u1 and u2 the more current is produced, is that correct? Are the differences in u1 and u2 caused by the type of materials used?

Its very interesting lecture. May i ask for an email address. I have few questions and probably future work. All Best
