Electrical Resistance: an Atomistic View
Papers | 26 Oct 2006 | Contributor(s):: Supriyo Datta
This tutorial article presents a “bottom-up” view of electrical resistance starting from something really small, like a molecule, and then discussing the issues that arise as we move to bigger conductors. Remark ably enough, no serious quantum mechanics is needed to understand electrical...

Notes on the Ballistic MOSFET
Papers | 08 Oct 2005 | 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. When...

Electrical Conduction through Molecules
Papers | 08 Jul 2003 | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes as well as...

Resistance of a Molecule
Papers | 29 Apr 2003 | Contributor(s):: Magnus Paulsson, Ferdows Zahid, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes [1, 2] as well as...
