The modern smartphone is enabled by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. Interestingly the same amazing technology has also led to a deeper understanding of the nature of current flow on an atomic scale.

This course aims to make these lessons from nanoelectronics accessible to anyone in any branch of science or engineering.

The course is comprised of 4 units covering the following topics:

UNIT ONE: The New Perspective

UNIT TWO: Energy Band Model

UNIT THREE: What and Where is the Voltage

UNIT FOUR: Heat & Electricity, Second Law and Information
