Lecture 3: Resistance-Ballistic to Diffusive
28 Jul 2011 | | Contributor(s):: Mark Lundstrom
The resistance of a ballistic conductor and concepts, such as the quantumcontact resistance, are introduced and discussed. The results are then generalized to treat transport all the way from the ballistic to diffusive regimes.

Molecular Dynamics Studies of Gaseous Transport
05 Apr 2006 | | Contributor(s):: Ki-Ho Lee, Jason Myers, Susan Sinnott
Carbon nanotubes (CNTs) have generated a great deal of interest due to their unique properties. In this study, we examine the transport properties of various nanotubes using REBO-MD to determine the effects of diameter and chirality on transport mode. Both oxygen and methane were diffused through...
