Abstract


The comparative study of chemical properties and electronic bond structure of amorphous carbon (a-C), hydrocarbon (a-HC), carbon nitride (a-CNx) and hydrogenated carbon nitride (a-HCNy) is reported here. The spectroscopic analyses suggest that the presence of oxide layer is not only the prime cause but the presence of nitrogen is partially responsible for the chemical shift towards higher binding energy. In x-ray photoelectron spectroscopy (XPS), C 1s spectra of a-HCNy film shows higher chemical shifts compare to a-C, a-HC and a-CNx. Raman spectra display a strong fluorescence effect of a-HC and a-HCNy where as a-C and a-CNx exhibits a promising G and D band at room temperature. Fourier transform infrared spectroscopy (FTIR) spectra show a large NH-OH over lapping region in a-HCNy compare to a-HC and a-CNx film whereas it is negligible in a-C. FTIR spectra show that the a-C, a-HC and a-CNx films are dominated by sp2 bonded region while a-HCNy is the mixture of sp2, sp3 and hydrogen bridging bond.
