Co-adsorption mechanism drives CO oxidation on defective ZnS
P. R. A. de Oliveira, C. Codeço, M. G. Menezes +3
Reactivity on wide-bandgap semiconductor surfaces relies critically on the generation of active sites. In the case of CO oxidation, however, the mere presence of defects is insuffi…

Insights into activation on defective ZnS surfaces
P. R. A de Oliveira, P. Venezuela, F. Stavale +1
In this work, we investigate activation on ZnS using Near Ambient-Pressure X-ray photoelectron spectroscopy measurements (NAP-XPS) and density functional theory calculatio…

In situ growth of a type-II ZnO/ZnS heterostructure:From stability to band-offset
P. R. A de Oliveira, I. Coelho, G. Felix +2
We have successfully obtained a ZnO/ZnS heterostructure by heating a ZnS(001) single crystal in a controlled impurities-free oxygen atmosphere. Combining X-ray photoelectron spectr…
