Abstract CNx films prepared by high dose ion implantation and post-annealing were studied by Auger electron spectroscopy, x-ray photoelectron spectroscopy and x-ray diffraction. A nearly uniform CNx layer was formed. Carbon and nitrogen were found covalently bonded in the films. X-ray diffraction results showed that two crystal phases of C3N4, β-C3N4 and p-C3N4, have been formed in the matrix of carbon.
