Paper Abstract

Diamond-like carbon (DLC) films were synthesized by KrF excimer laser irradiation of single-crystal Si substrates immersed in a cyclohexane liquid. The deposition process was performed with a peak laser power density of about 108 W/cm2 in open atmosphere at room temperature. Scanning electron microscopy (SEM), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) studies showed diamond-like characteristics of the deposited films. Optical emission spectroscopy (OES) of laser-induced plasmas of cyclohexane indicated decomposition of the cyclohexane molecules. A mechanism based on the dissociation of the cyclohexane molecules and condensation of energetic carbon atoms into diamond-like films was proposed to explain the process.
