Thickness and Roughness of Amorphous Carbon Thin Film

Abstract

The carbon part exists in a wide scope of designs, going the reach from jewel to graphite. Meager movies of carbon can be produced from the gas stage utilizing a plasma. Such slender movies of carbon, two or three micrometers thick, can contain a liberal proportion of Diamond-like carbon bonds, achieving high hardness. Thin films coatings have become a major study in the past decade which increased various studies in this field. The cathodic Arc system is used in our study for the deposition of the Amorphous tetrahedral carbon film on the cut stainless steel samples._x000D_ And the samples undergo Raman spectroscopy as Raman spectra of tetrahedral shapeless carbon (ta-C) films have been acquired as an element of impinging carbon particle energy. To break down the spectra quantitatively, the Raman spectra were fitted utilizing a least squares PC program_x000D_ The family member Raman power is found to diminish with expanding sp3/ sp2 holding proportion in the movies. Specifically, the boundaries from the fits show a solid relationship between the general power proportion and the sp3 portion. And the Profilometer gives the thickness and the roughness values of the ta-C films obtained from the Cathodic arc deposition which we study in this work The deposition will be carried out in two ways 1) Without Nitrogen as dopant 2) With nitrogen as a dopant. We will study how the roughness and thickness will be varying in the presence and absence of Nitrogen as the dopant.
