Book Description
Photoemission measurements have been made on single crystals of cadmium sulfide which were cleaved and tested in high vacuum at photon energies between 7.2 and 11.6 eV. The electron affinity is found to be 4.8 eV. Additional measurements have been made in an extended range from 6 to 21.2 eV using surfaces cleaved in air or in low vacuum and tested in low vacuum. The apparatus for cleaving and measuring photoemission is described. Important features of the band structure are deduced from the energy distribution and quantum yield measurements. Two conduction band maxima are located about 6.7 and 8.2 eV above the top of the valence band. Two valence band maxima are located about 1.2 and 9.4 eV below the top of the valence band. The effects of surface conditions on photoemission from cadmium sulfide have been studied by comparing measurements made on samples cleaved in high vacuum with the corresponding results from surfaces prepared by other techniques.

Photoemission Studies of the Electronic Band Structures of Gallium Arsenide, Gallium Phosphide, and Silicon

Languages : en
Pages : 328
Book Description
Photoemission studies of the electronic energy band structures of gallium arsenide, gallium phosphide, and silicon are reported. The results of measurements of photoemissive yield and energy distributions for photoemitted electrons, as a function of the photon energy of the monochromatic light, are presented for both clean surfaces of GaAs, GaP and silicon, and those surfaces covered with a monolayer of cesium to lower the vacuum level. The structure features of the energy distribution curves for photoemitted electrons for GaAs, GaP, and Si are explained in detail in terms of direct interband transitions in the respective electronic energy band structures of the materials. The overall photoemission results for the three materials are shown to be quite similar, which reflects the basic similarity of their electronic band structures and optical spectra.
