ECE 612 Lecture 7: Scattering Theory of the MOSFET I
Lecture 3A: The Ballistic MOSFET
10 Sep 2008 | Online Presentations | 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...
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.
Physics of Nanoscale Transistors: An Introduction to Electronics from the Bottom Up
Transistor scaling has pushed channel lengths to the nanometer regime, and advances in nanoscience have opened up many new possibilities for devices. To realize these opportunities, our...
Lecture 4: Scattering in Nanoscale MOSFETs
08 Sep 2008 | Online Presentations | Contributor(s): Mark Lundstrom
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...
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...
Lecture 1: Review of MOSFET Fundamentals
4.0 out of 5 stars
26 Aug 2008 | Online Presentations | Contributor(s): Mark Lundstrom
A quick review of the traditional theory of the MOSFET along with a review of key device performance metrics. A short discussion of the limits of the traditional (drift-diffusion) approach and...
Nano Carbon: From ballistic transistors to atomic drumheads
5.0 out of 5 stars
14 May 2008 | Online Presentations | Contributor(s): Paul L. McEuen
Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an...
Can numerical “experiments” INSPIRE physical experiments?
20 Dec 2007 | Online Presentations | Contributor(s): Supriyo Datta
This presentation was one of 13 presentations in the one-day forum,
"Excellence in Computer Simulation," which brought together a broad
set of experts to reflect on the future of...
MCW07 Modeling Molecule-Assisted Transport in Nanotransistors
06 Nov 2007 | Online Presentations | Contributor(s): Kamil Walczak
Molecular electronics faces many problems in practical device implementation, due to difficulties with fabrication and gate-ability. In these devices, molecules act as the main conducting channel....
The Nano-MOSFET: A brief introduction
17 Aug 2007 | Online Presentations | Contributor(s): Mark Lundstrom
MOSFET channel lengths are now well below 100nm, and getting smaller,
but MOSFETs are still modeled and understood much as they were 30
years ago. Seminal work in the 1960’s laid the...
ECE 612 Lecture 10: The Ballistic MOSFET

ECE 612 Lecture 11: The Quasi-ballistic MOSFET
Logic Devices and Circuits on Carbon Nanotubes
05 Apr 2006 | Online Presentations | Contributor(s): Joerg Appenzeller
Over the last years carbon nanotubes (CNs) have attracted an increasing interest as building blocks for nano-electronics applications. Due to their unique properties enabling e.g. ballistic...
Optimization of Transistor Design for Carbon Nanotubes
20 Jan 2006 | Online Presentations | Contributor(s): Jing Guo
We have developed a self-consistent atomistic simulator for CNTFETs.
Using the simulator, we show that a recently reported high-performance
CNTFET delivers a near ballistic on-current. The...
A 3D Quantum Simulation of Silicon Nanowire Field-Effect Transistors

As the device size of the conventional planar metal oxide semiconductor field effect transistor
(MOSFET) shrinks into the deep sub micron regime, the device performance significantly...
Simple Theory of the Ballistic MOSFET
11 Oct 2005 | Online Presentations | Contributor(s): Mark Lundstrom
Silicon nanoelectronics has become silicon nanoelectronics, but we
still analyze, design, and think about MOSFETs in more or less in the
same way that we did 30 years ago. In this talk, I...
