Abstract
The modifications of the (111) surfaces of a type-IIb natural diamond and a CVD diamond film upon annealing and exposure to atomic hydrogen have been examined by ultraviolet-excited (UPS) and X-ray-excited (XPS ) photoelectron spectroscopy. Besides the two surface configurations c ommonly described in the literature, i.e. the clean reconstructed surf ace and the one associated with a monohydride passivation, a third con figuration which evolves upon extreme hydrogen exposure has been obser ved.
