Abstract
Through a simple gas reaction, single-crystalline β-Ga2O3 nanoribbons, nanosheets andnanowires were synthesized on a large scale at 700 °C.They were characterized by means of x-ray powder diffraction(XRD), field emission scanning electron microscopy (FE-SEM),energy-dispersive x-ray spectroscopy (EDS), transmissionelectron microscopy (TEM), high-resolution transmissionelectron microscopy (HRTEM), selected-area electron diffraction(SAED) and Raman spectroscopy. FE-SEM and TEM images showedthat the product was composed of nanoribbons, nanosheets andnanowires. XRD, EDS, HRTEM, SAED and the Raman spectrum indicatedthat all of the nanoribbons, nanosheets and nanowires were of single-crystalline β-Ga2O3.
