Abstract

GaN nanostructures are grown using catalysis free chemical-vapor-deposition technique following vapour-solid growth mechanism. Nanostructures ranging from solid clusters, nanoprotruded microbelts, nanotips, and hollow nanotubes are demonstrated. Resonance Raman studies reveal wurtzite GaN phase with crystalline quality in these nanostructures. Raman area mapping is used to understand some of the noble morphological features. A detailed growth mechanism is described for the growth of these nanostructures.
