Electrical Resistance: an Atomistic View

26 Oct 2006 | Publications | 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 …
