Morphological control and kinetics in three dimensions for hierarchical nanostructures growth by screw dislocations

By programming synthesis conditions, we achieve a controllable 3D screw dislocation growth of previously unreported hierarchical hollow nanobelts via a facile CVD approach. More importantly, we propose a new 3D screw dislocation growth model with considering of transition in growth velocities and directions to interpret the formation of the nanobelts.176
