Photon-stimulated desorption of H+ and H- ions from diamond surfaces: Evidence for direct and indirect processes
Hoffman, A; Petravic, Mladen; Comtet, G; Heurtel, A; Hellner, L; Dujardin, G
Photon-stimulated desorption of positive and negative hydrogen ions from hydrogenated diamond film and Di(100) surfaces and amorphized diamond surface has been studied for incident photon energies in the 280-340 eV range. From comparison between the H+ yield as a function of photon energy and the near-edge x-ray absorption fine structure recorded by detecting secondary electrons of selected kinetic energies the processes leading to photodesorption are assessed. It is shown that desorption of H+...[Show more]
