Nanoscale mapping of sub-gap electroluminescence from step-bunched, oxidized 4H-SiC surfaces

Natalia Alyabyeva, Jacques Ding, Mylène Sauty +7

Scanning tunneling luminescence microscopy (STLM) along with scanning tunneling spectroscopy (STS) is applied to a step-bunched, oxidized 4H-SiC surface prepared on the silicon fac…
