Abstract
Large-scale β-Ga2O3 nanowires and individual β-Ga2O3 nanowires bridging adjacent metal Ag catalyst islands were synthesized on the unpatterned and patterned MgO single crystal substrates by direct reaction of gallium and water vapor. The samples were characterized by field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction (XRD), transmission electron microscopy and selected area electron diffraction. The results show that the line-like nanostructures are monoclinic β-Ga2O3 nanowires. The individual β-Ga2O3 nanowires are rooted in the islands, and some of them bridge adjacent islands of the Ag catalyst. This work offered the prospect of developing ultrafine nanoscale devices.
