摘要
Low-energy electron backscattering technique using a hypocycloidal electron spectrometer is applied to measure energy loss spectra at different incident electron energies from mirror-polished (I 11), (10 0) and (110) surfaces of Ge. The obtained results confirm and complement the available data on the energy position of the extrema of the density of both filled (below E-F) and empty (above EF) surface and bulk electron states in the reduced Brillouin zone for different surfaces of germanium.
