Electrostatic Tuning of the Coulomb Interaction in Single-Layer Graphene

ORAL

Abstract

The Landau-Fermi Liquid Theory maps an interacting liquid of electrons to a non-interacting gas of quasiparticles. This picture breaks down in Graphene, because the bare Coulomb interaction is preserved near the charge neutrality point. In this talk, I will discuss recent in-operando angle-resolved photoemission studies on single layer graphene where we directly visualize modifications of its electronic band structure upon tuning the Fermi Energy.
