dc.description.abstract | Hydrogen-terminated diamond is known for its unusually high surface conductivity that is ascribed to its negative electron affinity. In the presence of acceptor molecules, electrons are expected to transfer from the surface to the acceptor, resulting in p-type surface conductivity. Here, we present Kelvin probe force microscopy (KPFM) measurements on carbon nanotubes and C-60 adsorbed onto a hydrogen-terminated diamond (001) surface. A clear reduction in the Kelvin signal is observed at the position of the carbon nanotubes and C-60 molecules as compared with the bare, air-exposed surface. This result can be explained by the high positive electron affinity of carbon nanotubes and C-60, resulting in electron transfer from the surface to the adsorbates. When an oxygen-terminated diamond (001) is used instead, no reduction in the Kelvin signal is obtained. While the presence of a charged adsorbate or a difference in work function could induce a change in the KPFM signal, a charge transfer effect of the hydrogen-terminated diamond surface, by the adsorption of the carbon nanotubes and the C-60 fullerenes, is consistent with previous theoretical studies.
