| Outline of Final Research Achievements |
Photoemission measurements using the characteristic features of synchrotron radiation and laser have been performed to study the occupied and un-occupied electronic structure of graphene-related materials. Band dispersion with odd and even symmetry to the graphene layer have been determined for epitaxial graphene with the thickness of 1, 2 and 3 layers. Temporal electron population in pi* state of these graphene has been measured using time-resolved two-photon photoemission measurements. Oxygen intercalation causes p-type Dirac bands, strongly bounded image potential states and pi* state with longer lifetime. Bi(110) ultra-thin film with six in-plane domains have been grown on graphene and band dispersion alongΓX1 and ΓX2.have been determined.
