Copper oxide phases probed via plasmonic light emission in the STM
Luminescence spectroscopy with a scanning tunnelling microscope (STM) is employed to differentiate bulk-type Cu _2 O from a Cu _3 O _2 surface oxide at the nanometre scale. Although plasmonic modes in the tunnelling gap are responsible for the emission response in both cases, the luminescence cross-...
