The effect of argon and oxygen sputtering on carbon contaminant buildup on ZnO during XPS
نویسندگان
چکیده
The effect of argon and oxygen sputtering on carbon contaminant buildup on ZnO during XPS (X-ray photoelectron spectroscopy) analysis has been examined. Argon and oxygen sputtering cause a rapid decline in hydroxyl oxygen and contaminant carbon content at the surface. Reduc tion to metallic zinc is not observed. In a carefully baked instrument after sputtering a stable clean surface could be maintained over several hours of analysis.

Introducing Pt/ZnO as a new non carbon substrate electro catalyst for oxygen reduction reaction at low temperature acidic fuel cells
Gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (ORR). Because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. To this end, researchers have used platinum-coated carbon. In the present study, due to the reduction of carbon corrosion, Zinc oxide...

متن کاملReflectivity degradation of grazing-incident EUV mirrors by EUV exposure and carbon contamination
Reflectivity degradation of grazing-incident extreme ultraviolet (EUV) mirror samples by EUV exposure was investigated in a commercial XTS 13-35 EUV source. The roughness of EUV exposed samples increases with an increase in exposure time due to the erosion of sample surface by ions and neutrals, or deposition of contaminant such as carbon on the sample surface. While energetic debris certainly ...
متن کاملCoadsorption of Dioxygen and Carbon Monoxide on a Mg(100) Surface
The activation of carbon monoxide by oxygen on Mg(100) surface has been investigated by X-ray photoelectron spectroscopy (XPS). Carbon monoxide is only weakly adsorbed (dispersion-type forces) on a magnesium surface. The XPS result has shown that the dissociation of carbon monoxide leading to the formation of a metastable surface carbonate species occurs through the participation of an oxyg...

Structural, electrical and optical properties of indium tin oxide or ITO (In2O3:SnO2) thin films on different substrates are investigated. A 100-nm-thick pre-deposited zinc oxide (ZnO) buffer layer is utilized to simultaneously improve the electrical and optical properties of ITO films. High purity ZnO and ITO layers are deposited with a radio frequency sputtering in argon ambient with plasma p...
