Abstract
AbstractThe low energy electron dispersion in graphite is measured by angle‐resolved photoemission spectroscopy. The measured photoemission intensity maxima are compared to a tight‐binding calculation of the electronic band structure. We observe a strong trigonal warping of the equi‐energy contour which is well reproduced by the calculations. Furthermore we clearly show that the concept of Dirac Fermions breaks down for AB stacked graphite. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
