Hydrogenated diamond crystal C(100) conductivity studied by STM

Abstract The topographic and spectroscopic capabilities of the scanning tunnelling microscope (STM) have been used to explore the conductivity of hydrogenated diamond C(100)-(2 × 1) surfaces. It has been shown that the surface conductivity is determined by the interplay between various factors: the adsorption of atmospheric species on the surface, the doping concentration of the sample, the presence of sub-surface species and the presence of the top layer of hydrogen.
