Electronic structure of CdTe(110) as studied by angle-resolved photoemission

Abstract
Photoemission energy distributions from cleaved CdTe(110) surfaces have been measured in the Γ¯ X¯ and Γ¯ Y¯ azimuths for photon energies of 16.8 and 21.2 eV. Using a semiempirical band calculation, we were able to sort out the origin of the observed structures in terms of direct and indirect excitations in the bulk as well as contributions from the surface.
