Abstract:
We compute, from first principles, the dielectric function and electron energy loss spectrum (EELS) of an oxidized Si(100)(2×2) surface. The surface local field effect is found to be important for the calculation of EELS in a reflection geometry. Theoretical problems that arise when local fields are included within the periodic supercell approach are discussed in detail.
