Abstract
In this paper we review a number of works on photon stimulated ion desorption (PSID) ofhydrogen from various diamond surfaces. In particular, we elaborate on the bondingconfiguration of adsorbed hydrogen (deuterium) and its neighbouring atoms, and itsthermal stability in surface and sub-surface regions. Usage of hydrogen PSID as acharacterization method involves detailed description of the mechanism and dynamics ofhydrogen ion desorption initiated by a synchrotron generated photon beam. Severalcomplimentary analytical techniques (near edge x-ray absorption fine structurespectroscopy, x-ray photoelectron spectroscopy, secondary electron emission measurements)were used to clarify the results of the PSID measurements. The studied systems includehydrogenated/deuterated single-crystal and polycrystalline diamonds, diamond filmshydrogenated ex situ using microwave hydrogen plasma versus in situ hydrogenation bypassing hydrogen gas through a hot tungsten filament, hydrogenated diamond filmsexposed to atomic and molecular oxygen gas, and ion beam damaged diamond films.
