Doping and Polarization Dependence of the Thin Film C$_{60}$ Band Structure

ORAL

Abstract

Experimental electronic band structure studies of buckminsterfullerene (C$_{60}$) thin films derived from high-resolution angle-resolved photoemission spectroscopy (ARPES) measurements are examined with respect to new theoretical DFT band structure calculations of the unique low-dimensional structure. The dispersive band structure, substrate interaction, and potassium-doping effects are examined and quantified. Observed patterns with photon energy and polarization dependence are explained in terms of electron interactions within and between the buckyball molecules.
