Understanding Molecular Conduction
Online Presentations | 08 Jul 2004 | Contributor(s):: Supriyo Datta
It is common to differentiate between two ways of building a nanodevice: a topdown approach where we start from something big and chisel out what we want and abottom-up approach where we start from something small like atoms or molecules andassemble what we want. When it comes to describing...

Electronic Transport Through Self-Assembled Monolayers
Online Presentations | 25 Feb 2004 | Contributor(s):: Takhee Lee
Characterization of charge transport in molecular scale electronic devices has to date shown exquisite sensitivity to specifics of device fabrication and preparation. Thus, intrinsic molecular band structure has been problematic to extract from published results. Here we demonstrate...

Inelastic Effects in Molecular Conduction
Online Presentations | 12 Apr 2004 | Contributor(s):: Abraham Nitzan
Molecular electron transfer, as treated by the Marcus theory, strongly depends on nuclear motion as a way to achieve critical configurations in which charge rearrangement is possible. The electron tunneling process itself is assumed to occur in a static nuclear environment. In the application of...
