Simple Theory of the Ballistic MOSFET

19 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 will describe a simple analysis of the ballistic MOSFET. No MOSFET is truly ballistic, but …

MATLAB Scripts for "Quantum Transport: Atom to Transistor"

15 Mar 2005 | Downloads | Contributor(s): Supriyo Datta

Tinker with quantum transport models! Download the MATLAB scripts used to demonstrate the physics described in Supriyo Datta's book Quantum Transport: Atom to Transistor. These simple models are less than a page of code, and yet they reproduce much of the fundamental physics observed in experiments.

Homework for PN Junctions: Depletion Approximation (ECE 606)

09 Jan 2006 | Teaching Materials | Contributor(s): Muhammad Alam

This homework assignment is part of ECE 606 "Solid State Devices" (Purdue University). It contains 5 problems which lead students through a comparison of the depletion approximation and an exact solution of PN junction diodes. Students compute the exact solution by using the PN Junction Lab …

Notes on the Ballistic MOSFET

21 Nov 2005 | Publications | Contributor(s): Mark Lundstrom

When analyzing semiconductor devices, the traditional approach is to assume that carriers scatter frequently from ionized impurities, phonons, surface roughness, etc. so that the average distance between scattering events (the so-called mean-free-path, λ) is much shorter than the device. …

2005 Molecular Conduction and Sensors Workshop

25 May 2005 | Workshops

This is the 3rd in a series of annual workshops on Molecular Conduction. The prior workshops have been at Purdue University, W. Lafayette, IN (2003) and Nothwestern University, Evanston, IL (2004). The workshop has been an informal and open venue for discussing new results, key challenges, and …

Ballistic Nanotransistors

07 Dec 2005 | Learning Modules | Contributor(s): Mark Lundstrom

This learning module is an introduction to the theory ballistic nanotransistors. No transistor is fully ballistic, but analyzing nanotransistors by neglecting scattering processes provides new insights into the performance and limits of nanoscale MOSFETs. This learning module introduces the …

Geometry of Diffusion and the Performance Limits of Nanobiosensors

05 Dec 2006 | Online Presentations | Contributor(s): Muhammad Alam, Pradeep Ramachandran Nair

This presentation demonstrates how the classical diffusion-capture (D-C) model has improved sensor performance, since the D-C model is a "geometry of diffusion" rather than a "geometry of electrostatics." A scaling law based on D-C is also posited; the scaling law resolves many classical puzzles …

On the Reliability of Micro-Electronic Devices: An Introductory Lecture on Negative Bias Temperature Instability

03 Oct 2005 | Online Presentations | Contributor(s): Muhammad Alam

In 1930s Bell Labs scientists chose to focus on Siand Ge, rather than better known semiconductors like Ag2S and Cu2S, mostly because of their reliable performance. Their choice was rewarded with the invention of bipolar transistors several years later. In 1960s, scientists at Fairchild worked hard …
