Abstract

Nitrogenated carbon films were prepared on silicon substrates by cathodic electrodepositon from solutions of dicyandiamide (C2H4N4) in ethanol. The composition and structure of the films were characterized by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy. The results show that the incorporated nitrogen in the films is chemically bonded to carbon with C-N, C=N and C≡N bonds, and the concentration of the depositing solutions has a great effect on the films deposition. The films have good chemical inertness and mechanical properties. A hardness of 1200 HV has been measured.
