Description
The effect of various annealing treatments on the structure properties of crystalline silicon (c-Si) produced by the inverted aluminum induced crystallization of amorphous silicon (a-Si) films was studied. The surface morphology and grain size of c-Si films were observed by optical microscope, SEM and AFM. X-ray diffraction and Raman spectroscopy were used to study quantity of Si crystallization due to thermal annealing. Results showed that the c-Si with average grain size of 27 nm in a (111) orientation were obtained by the thermal annealing at 300 oC for 1 h. Prolonged heat treatment improved Si crystallite quality and increased the average grain size.
