Abstract

Diamond-like carbon (DLC) is emerging as a category of very important engineering material and its properties can be varied by tuning its sp3 hybridized bonds normally found in diamond. Amorphous carbon (DLC) films were deposited onto silicon substrate at room temperature in a vacuum chamber by Conventional Incidence Pulsed Laser deposition (CIPLD). Nd: YAG (1.064nm) laser pulses with duration of 14ns and intensity of 3.43x1012 w/cm2 was used. The effect of variety of process parameters on the film properties is investigated. Deposition at room temperature and high concentration of ions yield DLC structure of film. The microstructure of the deposited film was investigated by Scanning Electron Microscope (SEM). It was concluded that the deposited thin film was crystalline and non uniform.
