Diamond Surfaces with Air-Stable Negative Electron Affinity and Giant Electron Yield Enhancement

Diamond Surfaces with Air-Stable Negative Electron Affinity and Giant Electron Yield Enhancement

The presence of an air-stable negative electron affinity (NEA) on lithium-covered oxygen-terminated diamond after a thermal activation process is demonstrated. The NEA is unequivocally established by the onset of photoelectron yield at the bandgap energy of 5.5 eV. This surface exhibits a secondary...
