英文摘要The microcrystalline silicon films at different growth stages were deposited by plasma-enhanced chemical vapor deposition (PECVD). The reflectivity of grazing incidence X-ray from synchrotron radiation has been applied to investigate the evolution of surface roughness of these thin films. By study of surface morphology of microcrystalline silicon (mu c-Si: H), we understand their growth kinetics and growth mechanism. The results show that the growth exponent beta is 0.21 +/- 0.01 and 0.24 +/- 0.01 for mu c-Si: H films deposited on glass substrate at fixed substrate temperature, Under the following condition of electrode distance, pressure, if power density, H-2 dilutied at 200 degrees C to be 2 cm, 6.66 x 10(2) Pa and 0.22 W/cm(2), 99 % and 98 %, respectively. According to the KPZ model in the PECVD case the growth mechanism of the pc-Si: H films is a finite diffusion growth.
