In this work we aim to exploit the negative electron affinity of the surface of hydrogenated diamond combined with the efficient absorption of visible light by plasmonic nanoparticles to emit electrons using solar light. We postulate that by combining plasmonic nanoparticles with diamond it is possible to simultaneously increase the photoductivity of the diamond and to enhance photemission of electrons from the surface. The role of diamond defects in this process is discussed.

Abstract

In this work we aim to exploit the negative electron affinity of the surface of hydrogenated diamond combined with the efficient absorption of visible light by plasmonic nanoparticles to emit electrons using solar light. We postulate that by combining plasmonic nanoparticles with diamond it is possible to simultaneously increase the photoductivity of the diamond and to enhance photemission of electrons from the surface. The role of diamond defects in this process is discussed.
