Honeycomb chain-channel (HCC) signature in the calcium-induced - surface

The electronic and structural properties of a calcium-induced chain system on have been studied. Low-energy electron diffraction measurements clearly reveal a periodicity and the coverage is determined to be 1/6 monolayer. Angle-resolved photoemission measurements have been performed with two different light polarizations in order to study the symmetries of the surface states. In both polarizations no band crossing the Fermi level is found. The three detected surface state bands are in good agreement with theoretical calculations in the honeycomb chain-channel (HCC) model for an insulating case.
