Abstract

It is well known that nanomaterials are described by quantum laws. In this work quantum treatment for two metal contacts or diodes on a nanoscale was done. A useful expression for the input and output current is found by using the notion of the current density in quantum mechanics. The conditions required by this contact to act as a rectifier and amplifier are discussed. It found that certain restrictions should be imposed on the potential and the wave number for the metal contact to act as an amplifier. This requires the potential barrier to be positive this requires the region of incident current to have work function less than the transmuted one.
