Watching GaN nanowires grow

We report real-time transmission electron microscopy observations of the growth of GaN nanowires via a self-catalytic vapor-liquid-solid (VLS) mechanism. These nanowires nucleate and grow from Ga droplets formed during thermal decomposition of GaN at elevated temperatures in vacuum. This is the first direct observation of self-catalytic growth of nanowires via the VLS mechanism, and suggests new strategies for growth of semiconductor nanowires without unintentional doping.
