The appearance of the surface is very smooth due to the baking temperature increases. Some of the film's Crystal fusion, which corresponds to the research of W.Wang, et al [13].
The nature of the surface is more smooth. When the baking temperature increases. Crystalline thin films will be fused together. This is consistent with research W.Wang, et al. [13].
The characteristics of the surface are smooth. Because when the bake temperature increase. Crystals of some film will be melting together. According to the research, W.Wang et al. [13].
