Calculation of high resolution electron and helium energy loss cross sections using surface vibration spectral densities
Abstract
It is shown that vibrational eigenvectors (outputs of a slab calculation) are not required for the calculation of high resolution electron energy loss spectra (EELS) or helium energy loss spectra. Instead, vibrational spectral densities (outputs of a Green's function calculation) may be input directly to such calculations. This facilitates the treatment of scattering from bulk phonons as well as from surface phonons.
