Abstract:Polycrystalline silicon (poly-Si) thin films were obtained by aluminium induced crystallisation of amorphous silicon suboxide (a-SiOx, x = 0.22) via annealing of a-SiO0.22/Al bilayer structures at 550 °C for 4 - 30 h. The a-SiO0.22/Al thickness ratio was approximately 1. According optical microscopy measurements, the crystallized fraction reached the saturation value of 85% after annealing for 20 h. The further increase in the annealing time didn’t lead to an increase in this value. X-ray diffraction measureme… Show more
