Solid-state molecular rectifier based on self-organized metalloproteins

Electron-transfer proteins which can be used to fabricate biomolecular electronic devices exploiting their intrinsic redox properties, self-assembly capability, and surface charge distribution were shown. The first electronic device based on proteins in the solid state operating in air was demonstrated. The photocurrent spectrum measured on the devices indicates that the electron spectrum measured on the devices indicates that the electon-transfer mechanism through the Az redox site can be exploited to implement three terminal electronic and optoelectronic devices. A strong role in the conduction mechanisms seems to be played by the charge distribution of the molecular layer in the implemented solid-state devices.
