端氢金刚石表现出p型特征的表面导电性。然而，氢终止本身不足以促进这一效应，许多作者已经表明，需要包含特定电负性的吸附的水层来促进电子从表面向外扩散，从而在表面附近产生大量空穴。本文详细描述了该表面导电层在不同环境下的电学测量。讨论了这种传输机制的稳定性，并特别注意了器件的应用。
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.
