Characteristic energy band values and electron attenuation length of a chemical-vapor-deposition diamond (001)2 x 1 surface

The characteristic energy band values such as the Fermi-level position with respect to valence band top for a boron-doped p-type hydrogen-terminated chemical-vapor-deposition (CVD) diamond (001)2 x 1 surface and for a clean CVD diamond (001)2 x 1 surface have been determined by a new method with an accuracy of +/- 0.02 eV. The electron attenuation length for the clean diamond (00 1)2 x 1 surface for the electron kinetic energy of C 1s X-ray photoemission peak by Mg K alpha excitation is experimentally determined to be 2.1-2.2 nm. These values are compared and discussed with the previously reported experimental and simulation values. (C) 2009 Elsevier B.V. All rights reserved.
