## nanoHUB-U: Fundamentals of Nanoelectronics - Part B: Quantum Transport, 2nd Edition

Second in a two part series, this nanotechnology course provides an introduction to more advanced topics, including the Non-Equilibrium Green’s Function (NEGF) method widely used to analyze quantum transport in nanoscale devices. We will explore a number of topics within nanoelectronics, taking a more in depth look at quantum transport, gaining greater insight into the application of the Schrodinger Equation, and learning the basics of spintronics.

This self-paced course explains advanced fundamentals of nanoelectronics and mesoscopic physics.

First in the series, Fundamentals of Nanoelectronics, Part A: Basic Concepts,  is now available as a free self-paced course on edX and nanoHUB-U.

## Course Description:

Nanoelectronic devices are an integral part of our life, including the billion-plus transistors in every smartphone, each of which has an active region that is only a few hundred atoms in length.This nanotechnology course explains the fundamentals of nanoelectronics and mesoscopic physics.

Even with NO prior background in quantum mechanics, you should learn about cutting-edge developments and concepts that will prepare you for a future in nanotechnology and nanoelectronics.

Indeed we hope you will be excited to join the field and help invent the new devices that will shape the electronics of this century and meet its challenges.

## Prerequisites:

This course is intended to be broadly accessible to students in any branch of science or engineering. Students should have a basic familiarity with calculus, elementary differential equations, and matrix algebra. No prior acquaintance with quantum mechanics is assumed.
