Synthesis of gallium nitride nanostructures by nitridation

Gallium nitride (GaN) nanostructures were successfully synthesized by the nitridation of the electrochemically deposited gallium oxide (Ga2O3) through the utilization of a so-called ammoniating process. Ga2O3 nanostructures were firstly deposited on Si substrate by a simple two-terminal electrochemical technique at a constant current density of 0.15 A/cm2 using a mixture of Ga2O3, HCl,

Gallium nitride nanotube Wikipedia

History. Single crystal gallium nitride nanotubes were first reported to be synthesized by Peidong Yang and his research team at the University of Berkeley's Department of Chemistry on April 10, 2003. The synthesis was achieved by initially creating nanowires from pure crystals of zinc oxide onto a sapphire wafer through a process Yang and his colleagues previously created called epitaxial
