Chemistry, Physics and Technology of Surface| Summary: | The results of theoretical and experimental studies of oxygen and water adsorption effect on thermoelectric work function for GeS single crystals are presented. Surface bending of the energy bands under oxygen and water molecules adsorption has been determined in terms of the theoretical approach developed by W.A. Harrison based on LCAO and pseudopotential methods. Calculated values of surface bending of the energy bands under oxygen and water adsorption for GeS single crystals are in quantitative agreement with experimental values for thermoelectric work function changes obtained from the measurements of contact potential difference. |
