The influence of surface termination, defects, and adsorbates on the electronic properties of diamond surfaces is discussed. Hydrogen passivation leads to a negative electron affinity of diamond surfaces due to a dipole layer which is induced by the heteropolar carbon-hydrogen bonds of the surface atoms. This aspect is discussed quantitatively. Next, the role of surface defects is addressed and the correlation between the position of the surface Fermi level and the concentration of surface defects is discussed for p-type diamond. Finally, experiments combining total photoelectron yield spectroscopy and in situ conductivity measurements are reported which elucidate the phenomenon of surface conductivity of hydrogenated diamond. An electrochemical model is proposed to explain this unique feature of diamond surfaces.
