A researcher whose nucleation model with colleagues explains why a growing nanowire can adopt wurtzite even when the corresponding bulk semiconductor favors the zinc blende structure. Forming a new layer at the line where the catalyst liquid, solid wire and surrounding vapor meet changes the relevant interface-energy balance. The model predicts how a supersaturated solution can favor one structure during growth, connecting crystal form with the local growth mechanism.[ref]
