Abstract

The local structural properties of representative amorphous oxides, ZnO, HfO₂, ZrO₂, and In₂Ga₂ZnO₇ were investigated by using X-ray absorption spectroscopy and an ab-initio theoretical calculation (FEFF). The X-ray absorption near-edge structures of the amorphous systems were compared with those of their crystalline counterparts, and were interpreted in terms of weakened structural orders (in the case of ZnO, HfO₂, and In₂Ga₂ZnO₇) or fundamentally different local structures (ZrO₂; monoclinic-like local structure favoured in amorphous phase in contrast to the tetragonal structure in crystalline film).
