Electron Transfer and Electronic Conduction through an Intervening Medium

A new vision for ET: Electron-transfer (ET) processes in biological and synthetic materials (such as proteins and semiconductors, respectively) are of immense importance. A unified approach to describe these processes is useful in understanding, and controlling the various facets of electron transfer in condensed matter. The diagram shows a plot of the decay constant for the electron-tunneling process against the effective tunneling barrier in different materials.
