Abstract. In this paper we review our results on self-catalytic growth of InN nanowires, grown from In metal rich conditions by the Migration Enhanced Afterglow (MEAglow) technique. We present a short overview of the different growth methods that have been applied to produce InN nanowires and we discuss the self-catalytic growth mechanism for InN nanowires. We then present our experimental results on the self-catalytic and selective area growth of InN nanowires that show evidence for the nucleation and the growth mechanism of the InN nanowires under In metal rich conditions. Selective area growth on sapphire substrates is also discussed.
