Structural and Electronic Properties of Cobalt Germanide Islands on Ge(100)
The structure and electronic properties of cobalt germanide islands were studied by scanning tunneling microscopy (STM). We found that cobalt-rich surfaces (C-surface) and germanium-rich surfaces (G-surface) coexisted in the islands. Scanning tunneling spectroscopy (STS) confirmed that both surfaces displayed metallic characteristics. Structural models are suggested based on the bias-dependent STM images.
