| Research Abstract |
A main purpose of this study is an investigation of nano-scale conductance properties of few layer graphene films on SiC substrate. A precise control of layer numbers of graphene has been realized using low-energy electron microscopy. The local conductances of few layer graphene were measured using an integrated nanogap probe which was newly developed for this study. The measured results revealed a confinement effect in graphene nano-islands and a conductance modification near atomic step in continual graphene sheets. A lot of useful knowledge for future graphene electronics has been obtained.
