High Resolution Studies of the Electronic Properties of Graphite and Graphene

ORAL

Abstract

We report a high-resolution angle-resolved photoemission spectroscopy (ARPES) study on the electronic properties of bulk graphite and atomically-thin graphene layers. Data as a function of both in-plane and out-of-plane momenta, binding energy and photon energy will be presented. We have observed for the first time using ARPES some very interesting electronic properties near the Fermi energy E$_{F, }$which$_{ }$shows that interlayer coupling is an important ingredient in understanding the electronic properties of graphite. In addition, the unique electronic properties in atomically-thin graphene layers will be discussed and compared with those from the bulk graphite sample.
