摘要

Gallium oxide (Ga_2O_3) nanowires have been synthesized using a novel method by high-frequency inductive heating in a room temperature environment. Nanowires with high-yield were grown on silicon substrates in less than 3 min, using Ga_2O_3/graphite as the source powder. Scanning electron microscopy showed nanowire diameters of 20-40 nm and lengths up to several tens of microns, and high-resolution transmission electron microscopy verified the single-crystalline lattice of the nanowires. Electrical properties were investigated by connecting a single Ga_2O_3 nanowire in the field-effect transistor configuration. This demonstration further illustrates the feasibility of an easy and large-scale synthesis of nanomaterials by using high-frequency inductive heating.
