Thermodesorptive analysis of GaAs and ZnSe surfaces.
This paper concerns thermodesorption analysis of the interaction of ammonia, hydrogen, carbon dioxide and a mixture of H(2) + CO(2) with GaAs and ZnSe surfaces, to determine the strength and concentration of acid surface centres. The mechanism of interaction of the gases and surfaces has been examined. This work was aimed at differentiating between the strengths of acid centres on GaAs and ZnSe semiconductor surfaces to obtain more information about the quantity of hydrogen and carbon dioxide adsorbed, their energy characteristics, the presence or absence of dissociation, and the nature of the CO(2) hydration.(1).
