Hydrogenated amorphous carbon is one kinds of samples between diamond and graphite. It’s also called diamond-like carbon (DLC) or graphite-like carbon, which depends on the ratio of sp2 and sp3 contributions on density of states. As the diamond-like carbons become one of the important coating materials recently and are also applied to protect the object from external damage, a search to the most close to diamond-like carbon will help to improve the industrial application. In this work, the samples with and without doped with iron or nickel ion will be studied in terms of XPS results. The variation of the sp2/sp3 ratio will be used to characterize the properties of these hydrogenated carbon materials.

Hydrogenated amorphous carbon as well as diamond-like carbon (DLC) are mainly identified by the sp2, sp3 (and/or their ratio i.e. sp2/sp3) content present in the film. These films are widely used in coating technology and different electrical/electronic devices. In this present work, these carbon films are prepared with and without metal doping (iron, nickel and iron & nickel) using ethanolic solution of sucrose by the dip coating technique and are studied the electronic structure using x-ray photoemission spectroscopy spectra.

Hydrogenated amorphous carbon as well as diamond-like carbon (DLC) are mainly identified by the sp2, sp3 (and/or their ratio i.e. sp2/sp3) content present in the film. These films are widely used in coating technology and different electrical/electronic devices. In this work, we have present the electronic-bonding properties of different metal-doped (Fe, Ni, Fe-Ni) carbon thin films deposited by dip coating technique using ethanolic solution of sucrose with requisite (at%) amount of metal (Fe, Ni) chloride. For this study, we have employed the C, O K-edge and Fe, Ni L-edge x-ray absorption near edge structure (XANES) spectra and x-ray photoemission spectroscopy spectra. It is found that when Fe, Ni and Fe-Ni metal(s) are doped independently in carbon thin films then the local electronic bonding structure changed by the changing their sp2 and sp3 content.
