The metal–oxide–semiconductor field-effect transistor is a device used for amplifying or switching electronic signals. In MOSFETs, a voltage on the oxide-insulated gate electrode can induce a conducting channel between the two other contacts called source and drain. The channel can be of n-typeor p-type, and is accordingly called an nMOSFET or a pMOSFET (also commonly nMOS, pMOS). It is by far the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common. More information on MOSFET can be found here.
Lecture 7: Connection to the Bottom Up Approach
0.0 out of 5 stars
23 Sep 2008 | Online Presentations | 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...
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 2: Elementary Theory of the Nanoscale MOSFET
08 Sep 2008 | Online Presentations | 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...
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...
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...

2008 NCN@Purdue Summer School: Electronics from the Bottom Up
26 Aug 2008 | Workshops | Contributor(s): Muhammad A. Alam, Supriyo Datta, Mark Lundstrom
Electronics from the Bottom Up is designed to promote the bottom-up perspective by beginning at the nanoscale, and working up to the micro and macroscale of devices and systems. For electronic...
Physics of Nanoscale MOSFETs

26 Aug 2008 | Courses | Contributor(s): Mark Lundstrom
Transistor 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...
Lecture 1: Review of MOSFET Fundamentals
4.0 out of 5 stars
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...

With this exercise students are familiarized with the punchthrough effect, the series resistance at the source and drain region and the importance of impact ionization at high gate and drain bias...
How do I derive the 2D electron density used in nano MOSFET calculations?
Open | Responses: 1
In nanomos-2.5, the density of charge is obtained by multiplying the square of the wavefunction by a prefactor: with semiclassical method, that prefactor is given by
MOSfet Homework Assignment - Role of Dielectric Constant and Thickness
