11/10/2011· The Two Varieties of EG. Van Bommel first observed the differences between graphene grown on the silicon (0001) and the carbon (000–1) terminated faces of hexagonal silicon carbide. Low energy electron diffraction (LEED) and angle resolved photoemission spectroscopy (ARPES) reveals that Si-face graphene monolayers exhibit the characteristic linear bandstructure (a.k.a. Dirac cones).
