Abstract: | Crystalline quality of pulse-laser annealed micocrystalline silicon (poly-Si) films on yttria-stabilized zirconia [(ZrO_2)_<1-x>(Y_2O_3)_x: YSZ] crystallization-induction (CI) layers is further improved by a new two-step irradiation method, in which amorphous silicon (a-Si) films are irradiated using two kinds of energy density. Firstly, they were irradiated at a low energy density for a short time to generate nuclei, following by irradiation at a high energy density to complete crystallization. Crystalline fraction and grain size of the Si film crystallized by the two-step method were found to be larger while its FWHM was smaller than those by the conventional one. Moreover, grain size of the Si/YSZ/glass was more uniform than that of the Si/glass. This indicates not only effectiveness of the YSZ CI layer but also usefulness of the two-step method on improving Si film quality. |
