Gallium nitride nanotubes by the conversion of gallium oxide nanotubes

The future technology of blue lasers and optical communication, and is likely to be based on GaN. The creation of crystalline GaN nanotubes in bulk has been achieved by a two-stage process based on the well-controllable amorphous gallium oxide (Ga2O) nanotube conversion. The assynthesized GaN nanotubes have fairly uniform diameters of ≈80 nm, wall thicknesses of ≈20 nm, and lengths of up to several tens of micrometers.
