Lecture 7: Connection to the Bottom Up Approach
out of 5 stars
23 Sep 2008 | | Contributor(s):: Mark Lundstrom
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.

Lecture 6: Quantum Transport in Nanoscale FETs
12 Sep 2008 | | Contributor(s):: Mark Lundstrom
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...

Lecture 3A: The Ballistic MOSFET
10 Sep 2008 | | Contributor(s):: Mark Lundstrom
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...
Lecture 3B: The Ballistic MOSFET
This lecture is a continuation of part 3A. After discussion some bandstructure considerations, it describes how 2D and subthreshold electrostatics are included in the ballistic model.

Lecture 2: Elementary Theory of the Nanoscale MOSFET
08 Sep 2008 | | Contributor(s):: Mark Lundstrom
A very simple (actually overly simple) treatment of the nanoscale MOSFET. This lecture conveys the essence of the approach using only simple mathematics. It sets the stage for the subsequent lectures.
Lecture 4: Scattering in Nanoscale MOSFETs
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...
Lecture 5: Application to State-of-the-Art FETs
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.
Lecture 4A: Energy Exchange and Maxwell's Demon
02 Sep 2008 | | Contributor(s):: Supriyo Datta
Objective: To incorporate distributed energy exchange processes into the previous models from lectures 1 through 3 which are based on a "Landauer-like picture" where the Joule heating associated with current flow occurs entirely in the two contacts.Although there is experimental evidence that...
