ECE 656: Electronic Transport in Semiconductors

Instructor: Mark Lundstrom

This course is about how charge flows in semiconductors with an emphasis on transport in nanoscale devices. The objective is to develop a broad understanding of basic concepts. The course is designed for those who work on electronic materials and devices – whether they are experimentalists, device physicists, or computational experts. The course is intended to be accessible to students with a general, introductory background in semiconductors. The course consists of three parts. Part 1 reviews advanced semiconductor fundamentals reviewing concepts covered in 453/595 and 606 and addressing new topics such as carrier scattering. Part 2 addresses near-equilibrium transport in the presence of small gradients in the electrochemical potential or temperature, with or without the application of a small magnetic field. Finally, Part 3 examines high-field transport in bulk semiconductors and so-called “non-local” transport in nanoscale devices. Both semiclassical and quantum transport effects are discussed.
