  ABSTRACT: Al-induced crystallization yields the larger grain and (111)-orientation planes of poly-Ge thin film grown on SiO2 substrate, the (111)-orientation planes of poly-Ge thin film grown on SiO2 substrate are very important for the superior performance electronics and solar cells. We discussed the 50 nm thickness poly-Ge thin film grown on SiO2 substrate by Alinduced crystallization focusing on the lower annealing temperature and the diffusion control interlayer between Ge and Al thin film. The (111)-orientation planes ratio of poly-Ge thin film achieve as high as 90% by merging the lower annealing temperature (325℃) and the GeOx diffusion control interlayer. Moreover, we find the lack of defects on poly-Ge thin film surface and the larger average grains size of poly-Ge thin film over 12 μm were demonstrated by electron backscatter diffraction measurement. Our results turn on the feasibility of fabricating electronic and optical device with poly-Ge thin film grown on SiO2 substrate.
