Preparation of Ga2O3 nanoribbons and tubes by electrospinning

A simple way to synthesize β-Ga2O3 nanoribbons and tubes by electrospinning is introduced. The diameters of the electrospun fibers range from 150 nm to 2.5 μm and their lengths reach up to several millimeters. The relationship among precursors, precursor concentrations, and crystal growth of β-Ga2O3 nanoribbons and tubes are discussed. The structures of β-Ga2O3 fibers have been investigated by various methods such as thermogravimetric (TG) and differential thermal analysis (DTA), X-ray diffraction, FT-IR, Raman spectra, scanning electron micrograph (SEM), and transmission electron micrograph (TEM).
