Adaptive Graphene Electronics and Plasmonics

Lead Research Organisation: University of Southampton
Department Name: Optoelectronics Research Centre

Abstract

Graphene exhibits great potential for optoelectronic applications as its unique electronic bandstructure allows a high level of control over its electronic charge transport properties; however there is currently a lack of methods for controlling these properties in a spatially resolved, reversible and non-volatile manner. The project aims to demonstrate electrostatic doping of graphene on photorefractive lithium niobate; a material which allows for non-volatile, reversible charge distributions to be defined by structured illumination, and to explore the potential of this method for reconfigurable electronic interconnects and resonant plasmonic structures defined simply by optical illumination.

Description We have demonstrated for the first time an all-optical method for controlling the electronic properties of graphene, in a non-volatile yet reversible manner. Further, we have shown this mechanism can be used to tune meta-materials in the terahertz region.
Exploitation Route Our findings may be taken forward to develop optically responsive electronic systems and adaptable terahertz modulation devices based on tunable plasmonics. This could lead towards pharmaceuticals and biological monitoring systems where plasmonic devices are well established for molecular sensing and identification.
