Mapping the fermi surface of graphite with a display-type photoelectron spectrometer

Abstract

A display spectrometer is used to image the momentum distribution of photoelectrons from the Fermi level in graphite. The Fermi "surface" consists of six points at the corners K of the hexagonal, two-dimensional Brillouin zone, in agreement with band theory. The method is also applied to other equal energy surfaces below the Fermi level, thereby giving the band dispersion of the π-bands. © 1991 Springer-Verlag.
