Title:
Study on molecular devices with negative differential resistance 
Abstract:
This paper provides a first-principles study for the transport behavior of molecular devices exhibiting wide bias range of negative differential resistance (NDR). The devices are composed of a diphenyl-dimethyl connected to carbon chains from each side, which are then linked to gold electrodes through thiol-gold bond. The devices show an odd/even oscillating behavior: the NDR appears only for “odd” numbers of carbon atoms in the chain. We look at different device parameters in order to determine...    »
