摘要:用射频等离子体化学气相沉积(RF-PECVD)法在普通玻璃衬底上低温制备了μc-Si:H薄膜。采用快速光热退火炉(RTP),分别用低温(<650℃)和中温(<750℃)脉冲法(PRTP)对薄膜进行了退火处理。用拉曼光谱和扫描电子显微镜(SEM)研究了不同条件下退火薄膜散射谱的特征和表面形貌。结果显示,脉冲退火法晶化的薄膜,晶化率达到了53%,部分颗粒团簇的尺寸已达到200nm左右。用声子限域理论和表面尺寸效应对薄膜频谱的"红移"和"蓝移"现象进行了分析。
μc-Si:H films were deposited on common glass substrate by radio frequency plasma enhanced chemical vapor deposition ( RF-PECVD), then low temperature ( 〈 650℃) conventional rapid thermal processing and middle temperature ( 〈 750 ℃ ) pulsed rapid thermal processing had been used for the solid-phase crystallization (SPC) of μc-Si : H films. The scattering spectrogram and surface morphology of films were investigated through Raman and SEM. The result showed that the film has better crystallinity, the crystallinity of the film is 53 % and the size of some cluster grains are about 200 nm. The red-shift and blue-shift phenomenon were analyzed using the surface effects and the phonon confinement theory.
