Mon, 24 Jul 2017 01:05:32 +0000HUBzero - The open source platform for scientific and educational collaborationTransistor scaling has pushed channel lengths to the nanometer regime where traditional approaches to MOSFET device physics are less and less suitable 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. lecture 1 reviews traditional MOSFET theory, and Lecture 2 presents the new approach in its simplest form. Lectures 3A and 3B describe the mathematical treatment of ballistic …nanoHUB.orgsupport@nanohub.orgnonanotransistors, nanoelectronics, ballistic MOSFET, transistors, MOSFET, ballistic transport, short course, drift-diffusion, bottom up approachMark Lundstromen-gbCopyright 2017 nanoHUB.orgResourcesLecture 2: Elementary Theory of the Nanoscale MOSFET

http://nanohub.org/resources/5309
The IV characteristic of the ballistic MOSFET is formally derived. When Boltzmann statistics are assumed, the model developed here reduces to the one presented in Lecture 2. There is no new physics in this lecture - just a proper mathematical derivation of the approach that was developed intuitively in Lecture 2.http://nanohub.org/site/resources/2008/09/05395/2008.07.22-l3a-lundstrom.mp3The IV characteristic of the ballistic MOSFET is formally derived.

http://nanohub.org/resources/5311
No MOSFET is ever fully ballistic - there is always some carrier scattering. Scattering makes the problem complicated and requires detailed numerical simulations to treat properly. My objective in this lecture is to present a simple, physical picture that describes the essence of the problem and that allows us to interpret the results of detailed simulations.http://nanohub.org/site/resources/2008/09/05381/2008.07.23-l4-lundstrom.mp3No MOSFET is ever fully ballistic - there is always some carrier scattering.

The previous lessons may seem a bit abstract and mathematical. To see how this all works, we examine measured data and show how the theory presented in the previous lessons help us understand the operation of modern FETs.http://nanohub.org/site/resources/2008/09/05385/2008.07.23-l5-lundstrom.mp3The previous lessons may seem a bit abstract and mathematical.

http://nanohub.org/resources/5314
While the previous lectures have been in the spirit of the bottom up approach, they did not follow the generic device model of Datta. In this lecture, the ballistic MOSFET theory will be formally derived from the generic model for a nano-device to show the connection explicitly.http://nanohub.org/site/resources/2008/09/05474/2008.07.24-l7-lundstrom.mp3While the previous lectures have been in the spirit of the bottom up approach, they did not follow the generic device model of Datta.

http://nanohub.org/resources/5313
The previous lessons developed an analytical (or almost analytical) theory of the nanoscale FET, but to properly treat all the details, rigorous computer simulations are necessary. This lecture presents quantum transport simulations that display the internal physics of nanoscale MOSFETs. We use these results to elucidate the physics discussed in previous lessons and to identify issues that still need to be clarified.http://nanohub.org/site/resources/2008/09/05438/2008.07.24-l6-lundstrom.mp3The previous lessons developed an analytical (or almost analytical) theory of the nanoscale FET, but to properly treat all the details, rigorous computer simulations are necessary.
