Low-Energy Electron Loss Studies of CuInSe sub 2 Surfaces

The low energy loss spectra (LELS) of clean and oxygen contaminated (111) p-type CuInSe sub 2 single crystals are reported. Losses due to interband transitions and plasmon excitations are observed. By varying the primary electron energy (100-500 eV) both surface and bulk features of the conduction b...

Description
Summary:The low energy loss spectra (LELS) of clean and oxygen contaminated (111) p-type CuInSe sub 2 single crystals are reported. Losses due to interband transitions and plasmon excitations are observed. By varying the primary electron energy (100-500 eV) both surface and bulk features of the conduction bands are probed. As oxygen is absorbed on the surface of the CuInSe sub 2 (at room temperature), the In and Se atoms seem to associate with themselves and with oxygen, whereas the Cu atoms do not seem to play a direct role in the oxidation process. LELS spectra are presented as a function of primary beam energy and oxygen adsorption. 21 ref.--AA
