Abstract:
Reports the crystallization of amorphous silicon (a-Si) thin film by aluminum-induced crystallization (AIC) on glass substrates. The influence of annealing temperature and time on the crystalline of the sample are studied by X-ray diffraction(XRD), optical microscope(OM) and atomic force microscopy (AFM). The results show that the sample is still amorphous after annealing at 300℃, and at 400℃ the samples begin to crystallize and both the crystalline volume fraction and size of crystalline grain increase with annealing time increase. However, the roughness of the samples is also increased.
