Electron beam dissociation of CO and CO2 on ZnS thin films

摘要: The effects of electron bombardment in 10−6 Torr CO or CO2 upon the surface composition ZnS thin films was determined with Auger spectroscopy. stable 1×10−9 residual vacuum for and exposures without bombardment. With both present, C deposited S decreased, but no O accumulated on surface. This interpreted as an beam stimulated reaction which dissociated by reformed leaving For CO2, were increased while reduced. a involving dissociation reformation COx data suggest that did not occur when sample temperature from 30 °C to 150–200 °C. At 300 °C, diffused substrate consequences these reactions cathodolumin...
