Graphene-based Remote Controlled Molecular Switches

“This paper essentially gives an additional remote control to a graphene-based electrical device simply by the exposure to light at specific wavelengths.” says Prof. Samorì “This is the first step towards the development of graphene-based multicomponent materials and their use for the fabrication of multifunctional devices – if you imagine a sandwich-like multi-layered structure with graphene sheets separated by multiple layers each one integrating a different functional molecular component. Each functional component therefore imparts a new stimuli-responsive character to the material which can respond to different independent inputs like light, magnetic field, electrochemical stimuli, etc, leading to a multi-responsive graphene based nanocomposite”.
