Intercalant dependent electronic structure studies on alkali metal intercalated graphite compounds

ORAL

Abstract

We present electronic structure study results on various alkali-metal intercalated graphite compounds (GIC) using angle-resolved photoemission spectroscopy(ARPES). There are two competing theories on where the superconductivity occurs in this material; intercalant metal or charge doped graphene layer. To elucidate this issue, we measured electron doping amount of each alkali-metal intercalated GICs. In addition, there are some mysterious problems that can't be explained with current theories.
