Ion channeling in textured polycrystalline diamond films

Abstract
Channeling of H+ and H2+ ions of energies between 1.0 and 2.0 MeV in 〈100〉-textured polycrystalline diamond films grown by microwave plasma-assisted chemical-vapor deposition has been observed with Rutherford backscattering. The width of the orientational distribution of the diamond crystallites as deduced from the measured projectile velocity dependence of the observed channeling angular scans amounted to about 1°.
