Role of surface structure in photoelectron emission from solid Ne: impurities, defect and low-coordinated sites

Role of surface structure in photoelectron emission from solid Ne: impurities, defect and low-coordinated sites

Electron emission was obtained from a solid Ne sample growing from the gas phase on a low temperature substrate. The surface of the sample was irradiated by the light of an open-source microwave discharge running in the gaseous Ne. The irradiation produces electron emission from the sample. A seco...
