Switching and rectification of a single light sensitive diarylethene molecule sandwiched between graphene nanoribbons

By Fernando Vázquez Luna

The diarylethene molecule show two bistable states one for open and one for closed, it can be converted from one state to the other upon photo-exictation showing drastically different current-voltage characteristics when sandwiched between two graphene nanoribbons. There is a strong rectificaction behavior of the closed molecule isomer when one graphene nanoribbon is metallic and the other one semiconducting. Results presented in this paper may form the basis for a new class of molecular electronic devices
