摘要：

The work function and photoemission from p-type CdTe(100) single-crystal phosphorus doped to approximately 10(15) CM-3 and crystals that were subsequently highly doped to approximately 10(19) cm-3 with Li and covered with submonolayers of Cs were studied. In some instances the cesium-coated surfaces were modified by deposition of oxygen. Large work-function changes were found in CdTe at the initial deposition stages of Cs indicating the formation of large dipole moments on the CdTe(100) substrate. Band-gap-limited (at 1.56 eV) long-wavelength photoemission was observed from the above samples. The total spectral photoemission for visible and near-infrared regions was determined.
