dc.description.abstractA twin-plane based nanowire growth mechanism is established using Au catalyzed Ge nanowire growth as a model system. Video-rate lattice-resolved environmental transmission electron microscopy shows a convex, V-shaped liquid catalyst-nanowire growth interface for a <112> growth direction, that is composed of two Ge {111} planes which meet at a twin boundary. Unlike to bulk crystals, the nanowire geometry allows steady state growth with a single twin boundary at the nanowire centre. We suggest that the nucleation barrier at the twin-plane reentrant groove is effectively reduced by the line energy, and hence the twin acts as a preferential nucleation site that dictates the lateral step flow cycle which constitutes nanowire growth.
