Comparative Study of Ion Desorption from Clean and Contaminated TiO2(110) Surfaces by Slow Positron Impacts

We have compared positron-annihilation-induced ion desorption from clean and contaminated TiO2 surfaces. While O+ ions from the clean surface were detected, H+ ion desorption was observed for the contaminated surface. These results indicate that positron-stimulated desorption is sensitive to changes...

Zusammenfassung:We have compared positron-annihilation-induced ion desorption from clean and contaminated TiO2 surfaces. While O+ ions from the clean surface were detected, H+ ion desorption was observed for the contaminated surface. These results indicate that positron-stimulated desorption is sensitive to changes in the surface environment. [DOI: 10.1380/ejssnt.2015.261]
