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...
