Site-specific surface interaction of adsorbed H2O and halogens on CuInSe2 surfaces

The interaction of adsoorbed H 2 O, I 2 , and Cl 2 on cleaved CuInSe 2 surfaces has been investigated in ultrahigh vacuum to model semiconducteur/electrolyte interfaces. The semiconducteur/adsorbate system has been characterized by UV and X-ray photoelectron spectroscopy (UPS,XPS), low-energy electron diffraction (LEED), low-energy ion scattering spectroscopy (LEISS) and surface photovoltage measurements (SPV).
