| Research Abstract |
Unoccupied electronic band structure and ultra-fast electron dynamics on graphite and epitaxial graphene grown on SiC have been studied by time- and angle-resolved photoemission and synchrotron radiation photoemission measurements. The momentum-resolved lifetime of IPS electrons on graphite and electron dynamics in 3.14* state of epitaxial graphene with the thickness between 1 and 3 MLs have been elucidated.
