Crystallization, Phase Stability, Microstructure, and Chemical Bonding in Ga₂O₃ Nanofibers Made by Electrospinning.

ABSTRACT: We report on the crystal structure, phase stability, surface morphology, microstructure, chemical bonding, and electronic properties of gallium oxide (Ga₂O₃) nanofibers made by a simple and economically viable electrospinning process. The effect of processing parameters on the properties of Ga₂O₃ nanofibers were evaluated by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Thermal treatments in the range of 700-900 °C induce crystallization of amorphous fibers and lead to phase stabilization of α-GaOOH, β-Ga₂O₃, or mixtures of these phases. The electron diffraction analyses coupled with XPS indicate that the transformation sequence progresses by f
