摘要
<正> By using strong hydrogen dilution of silane in PECVD system and controlling the deposition parameters strictly, we have prepared a-Si:H and nc-Si:H as well as μc-Si:H films respectively. The structural characters of nc-Si: H films detected by means of HREM, Raman and X-ray diffraction spectra are identified as coinciding with the known definition of nanometer solids. The unique electrical and optical properties of nc-Si:H films are considered as the consequence of its novel structures.
