Introduction to Quantum Transport (edX)
This course introduces the non-equilibrium Green’s function (NEGF) method widely used to describe quantum effects in nanoscale devices, along with its applications to spintronic devices. This course introduces the Schrödinger equation, using the tight-binding method to discuss the concept of bandstructure and E(k) relations, followed by an introduction to the NEGF method with simple illustrative examples. Concept of spinors is introduced along with the application of the NEGF method to spintronic devices.
