Kinetic energy influence of hyperthermal dual ion beams on bonding and optical properties of carbon nitride films

Abstract
Carbon nitride films were produced by simultaneous irradiation of well-defined hyperthermal (50–400 eV), isotopically mass-separated 12C2 and 14N+ ions with various kinetic energy combinations. It was found that the intensity of CN-triple bonds normalized by the amount of nitrogen atoms in the films and the complex refraction index (n,k) are correlated with the energy combination of 12C2 and 14N+ ions.
