Paper Abstract

Pulse laser ablating graphite is adopted to deposit SiC films on Si(111) under different laser fluence and substrate temperature. Experiment results show that the deposited films present different morphology and X-ray diffraction characteristics. Single crystalline SiC is obtained when the laser fluence is 10J/cm2 and the deposition temperature is 900 degree(s)C. At lower laser fluence or lower substrate temperature, a carbon overlayer is formed. Meanwhile the surface roughness of the films becomes relative smooth and the deposition rate increase with laser fluence. The stress accumulation during film growth releases gradually as the substrate temperature increase. The mechanism of the crystalline SiC formation in the initial stage that the energetic carbon species penetrate several layers below the silicon surface by subplantation and transversely migration in silicon substrate is discussed. All the results suggest that the energy of incident atom play an important role in growth silicon carbon at low substrate temperature.
