▲ [16p-315-9] Direct nano-patterning of graphene by Anderson localization
Keywords:Helium ion micropcopy, Anderson localization, graphene
Irradiation of single-layer graphene (SLG) with accelerated helium ions (He+) controllably generates defect distributions, which create a charge carrier scattering source within the SLG. We report direct experimental observation of metal-insulator transition in SLG on SiO2/Si substrates induced by Anderson localization. This transition was investigated using scanning capacitance microscopy (SCM) by monitoring the He+ dose conditions on the SLG.
