The electronic structure of CVD diamond surfaces has been studied by core level and valence band photoelectron spectroscopy. Upon annealing at 870 °C, a band of surface states appears within the top 6 eV of the valence bands which is accompanied by a decrease in spectral intensity around 9 eV and a band bending of 0.4 eV. Similar changes could be induced by Ar ion bombardment. Exposure to atomic hydrogen largely restored the original spectra. These observations are compared with corresponding data on single-crystalline diamond surfaces. Similarities and differences are discussed in terms of structural models of the CVD diamond surface. © 1994.
