Paper
Single-crystalline (
01)β-Ga2O3 nanowires were grown by using a flexible GaN seed nanocrystal “self-organizing” around catalytic Pt droplets. The atomic structures of β-Ga2O3(
01) epitaxy on GaN(0001) were investigated by X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, Raman spectroscopy, and cathodoluminescence (CL). The synthesized nanowires prepared by self-consistent growth are single crystals of pure β-Ga2O3 phase with (
01)-orientation and high crystalline quality and have intense ultraviolet–blue CL emission properties at room temperature.
