Performance advantages and cost benefits are the driving forces behind the adoption of any newly maturing technology.GaN,in this respect,has come a long way in establishing itself as commercially viable technology with promising applications in UV and visible optoelectronics (1-2).The recent research trend for miniaturisation by developing one-dimensional structures such as nanowires,nanorods and nanopillars,of semiconducting materials is on the frontiers.GaN nanostructures are the building blocks for nano-devices (3) which are synthesised by different methods such as laser assisted catalytic growth,template assisted synthesis (4),sublimation (5),direct reaction of Ga and NH_3 (6) and MOCVD (2).
