Crystallographically driven Au catalyst movement during growth of InAs/GaAs axial nanowire heterostructures
The movement of Au catalysts during growth of InAs on GaAs nanowires has been carefully investigated by transmission electron microscopy. It has been found that Au catalysts preferentially stay on { 112 } B GaAs sidewalls. Since a {112} surface is composed of a {111} facet and a {002} facet and sinc...
