Light Emission from Single Oxygen Vacancies in Cu 2 O Films Probed with Scanning Tunneling Microscopy

Global photoluminescence (PL) and spatially resolved scanning tunneling microscopy (STM) luminescence are compared for thick Cu O films grown on Au(111). While the PL data reveal two peaks at 750 and 850 nm, assigned to radiative electron decays via localized gap states induced by O vacancies, a wid...
