The SiC(0001) 3× 3 surface state
Abstract
An angle resolved photoemission study of the surface state on the 6H-SiC(0001) 3× 3 surface is reported. The symmetry of the surface state is determined and effects induced after oxygen and sodium exposures are investigated. The periodicity of the surface dispersion is investigated in two different azimuthal directions. The expected 3× 3 periodicity of a Mott-Hubbard ground state was not observed when going outside the first 3× 3 Surface Brillouin Zone.
