Non-equilibrium and relaxation phenomena in graphene-based devices

Lead Research Organisation: Lancaster University
Department Name: Physics


Graphene (a single atomic layer of graphite) first experimentally isolated and identified only four years ago, is rapidly revealing its great potential as an important material for future electronic devices. In order to progress towards realistic device applications of graphene, it is important to address the issues which will affect the operation of graphene in real circuits, where high currents will lead to overheating and non-equilibrium charge carrier distributions. The proposed joint project will launch an internationally leading programme involving three research groups which are already well established in graphene research and have expertise in complimentary areas. By combining fabrication technology of graphene-based devices, transport and optical studies, and theoretical modelling, we will investigate the kinetic properties of charge carriers and phonons (lattice vibrations) in graphene over a broad range of operating voltages, temperatures and optical intensities, with the aim to establish and improve the operating characteristics of graphene-based electronic and optoelectronic devices.

Description Theory of quantum transport and quantum kinetics of electrons in graphene has been developed.
Exploitation Route Theory of quantum transport and quantum kinetics of electrons is used by many experimental groups to interpret their findings in this material and in graphene-based nanostructures. In particular, our predictions of Raman scattering accompanied by the excitation of electron-hole pairs in Landau levels of monolayer and bilayer graphene have been confirmed by the experiemnts performed at LNMCI-CNRS in Grenoble.

Description The observation of 10-digit accuracy of Hall resistance quantisation in graphne/SiC system and understanding of the reason for superior properties of graphene/SiC for quantum resistance standard development have enabled NPL to set this systems as funda,mental resistance standard and Oxford Instruments start developing table-top push-button quantum resistance standard instrument.
