Abstract
AbstractHydrogen terminated diamonds exposed to atmosphere typically exhibit surface p‐type conduction, thought to be due to transfer doping with holes in the surface valence band and negatively charged counter‐ions in an adsorbed layer. The effect has been demonstrated with atmospheric contamination forming an aqueous layer, and by C60 molecules. In this paper we show using first‐principles computational methods that organic layers made up from DDQ molecules may also be a candidate for inducing holes in the diamond surface. The effect appears independent of surface orientation and surface coverage. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
