โฆ Synopsis
We followed the surface oxidation of a 7-nm Co layer epitaxied on sapphire as a function of the oxygen coverage. Ultra-violet photoemission spectroscopy, atomic force microscopy and scanning tunneling microscopy were used to determine the thickness, surface roughness and electronic gap of the Co oxide.
