PHOTOELECTRON SPECTROSCOPY FOR VALENCE BAND OF SILVER AND GOLD FILMS ON GALLIUM ARSENIDE
砷化镓上银和金膜的价带光电子谱

New data about photoemission spectra of silver on GaAs (110) cleavage surface have been found by measurement at hv=21.2eV, 40.8eV, and 1486.6eV. Some additional data of gold on GaAs are also obtained. The thickness of evaporated Ag and Au films used for measurement ranged from 0.1? to 1000?.A maximum in the functional relation between the intensity of UPS valence spectra and the thickness of film has been noted and discussed.
