Self-catalytic growth of InN nanopillars on (0001) sapphire is reported under In-rich conditions, using the Migration Enhanced Afterglow (MEAglow) growth technique. The nanopillars are up to 2 μm in length and 100-200 nm in diameter, terminated with an In-metal droplet on the top, with growth direction and preferred orientation along the InN c-axis. The shape of the nanopillars is cylindrical and their diameter is determined by the diameter of the In-metal droplet. X-ray diffraction measurements indicate the presence of both cubic and hexagonal InN, with very good crystalline quality. The room temperature Raman spectrum shows the presence of the A1(TO), E2(high) and A1(LO) phonon modes of the hexagonal InN.
