Control of Graphene's Properties by Reversible Hydrogenation: Evidence for Graphane

R. R. Nair’s contribution to this work includes preparation and initial characterisation of graphene on SiO2 and graphene membranes. He carried out comparative Raman-spectroscopy studies of hydrogenated graphene on substrate and hydrogenated graphene membranes. He also studied the effect of varying the number of graphene layers on the resulting hydrogenation using Raman spectroscopy. Last, but not least, he discovered the atomic structure of fully hydrogenated graphene membranes called graphane with electron diffraction techniques in a transmission electron microscope.
