Abstract

Hydrogen terminated diamond exhibits surface conductivity of a p-type character. However, hydrogen termination itself is not sufficient to promote this effect and it has been shown by various authors that an aqueous layer containing adsorbates of a particular electronegativity is required to promote electron out diffusion from the surface, thus creating a population of holes in the vicinity of the surface. This paper describes detailed electrical measurements on this surface conductive layer in various environments. The stability of this transport mechanism with particular attention to device applications is discussed.
