Overview

The transistor has been called the greatest invention of the 20th century – it enables 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. If you are interested in understanding how this scientifically interesting and technologically important nano-device operates, this course is for you!

This nanotechnology course provides a simple, conceptual framework for understanding the essential physics of nanoscale transistors.  It assumes only a basic background in semiconductor physics and provides an opportunity to learn how some of the fascinating new discoveries about the flow of electrons at the nanoscale plays out in the context of a practical device.

The course is divided into four units:

  • Transistors fundamentals
  • Transistor electrostatics
  • Ballistic MOSFETs
  • Transmission theory of the MOSFET

The first two units provide an introduction for students with no background in transistors or a quick review for those familiar with transistors.  The third unit treats the ballistic transistor in which electrons move without resistance (in the traditional sense). The last unit uses that Landauer Approach to electron transport, which was developed to understand some striking experiments in nanophysics, to develop an understanding of how electrons flow in modern nanotransistors.  This short course describes a way of understanding MOSFETs that is much more suitable than traditional approaches when the channel lengths are of nanoscale dimensions. Surprisingly, the final result looks much like the traditional, textbook, MOSFET model, but the parameters in the equations have simple, clear interpretations at the nanoscale.

My objective for this course is to provide students with an understanding of the essential physics of nanoscale transistors as well as some of the practical technological considerations and fundamental limits. The goal is to do this in a way that is broadly accessible to students with only a very basic knowledge of semiconductor physics and electronic circuits. The course is designed for anyone seeking a sound, physical, but simple understanding of how nanoscale transistors operate. The course should be useful for advanced undergraduates, beginning graduate students, as well as researchers and practicing engineers and scientists.

This course is the latest in a series offered by the nanoHUB-U project which is jointly funded by Purdue and NSF with the goal of transcending disciplines through short courses accessible to students in any branch of science or engineering. These courses focus on cutting-edge topics distilled into short lectures with quizzes and practice exams.

I liked Unit 1 and 2, it is good refreshing of some important conceptions about semiconductors, about MOSFET's structure and working principles, and about modern transistror technology.

in Unit 3 and 4, sometimes it feels like there too much maths, that it's too dry and some lively analogy would be welcomed, to make a more lasting impression in mind.

But overall, I would say that Professor Lundstrom can explain the material well, in an accessible form.

Thanks to him and the whole team at Purdue University for this course.
