photoemission study of alkali halide/Si and alkali halide/LiBr interfaces

摘要

photoemission spectra obtained during the NaCl and KF deposition on a clean Si(lO0) surface and a LiBr/Si Rare reported. The electronic structure of the interfaces between two different alkali halides as well as between alkali halide and silicon is deduced from the experiments. Large negative electron affinity values have been found for the KF and NaCl films deposited on a Si(lO0) surface. # 1997 Elsevier Science Ltd. All rights reserved
