nanoHUB-U MOSFET Essentials L3.1: MOS Electrostatics - Energy Band Diagram Approach

This video is part of the course "Fundamentals of Transistors" taught by Mark Lundstrom at Purdue University. The course can be found on nanoHUB.org at nanohub.org/co... or on edX at www.edx.org/co... The transistor has been called the greatest invention of the 20th century - it enabled the electronics systems that have shaped the world we live in.
Today's nanotransistors are a high volume, high impact success of the nanotechnology revolution. This is a course on how this scientifically interesting and technologically important device operates. The course is designed for anyone seeking a sound, physical, intuitive understanding of how modern transistors operate. Important technology considerations and applications of transistors are also discussed. The focus is on MOSFETs for digital logic, but analog applications and other types of transistors are briefly considered.
This course is broadly accessible to students with only a very basic knowledge of semiconductor physics and electronic circuits. Topics include device metrics for digital and analog circuits, traditional MOSFET theory, the virtual source model, 1D and 2D electrostatics, Landauer/transmission approach to nanotransistors, the limits of MOSFETs, as well as a quick look at HEMTs, bipolar transistors, and compact circuit models. The course should be useful for advanced undergraduates, beginning graduate students, as well as practicing engineers and scientists.
