Influence of the Crystal Structure of the Nucleus on the Morphology of t-ZnO Tetrapods

A new approach to simulating the morphology of hierarchical nanocrystals has been proposed on the example of ZnO nanotetrapods. Within this approach, twinning is considered as a point of symmetric growth bifurcation under unstable conditions. The electronic structure has been calculated for elementa...

Description
Summary:A new approach to simulating the morphology of hierarchical nanocrystals has been proposed on the example of ZnO nanotetrapods. Within this approach, twinning is considered as a point of symmetric growth bifurcation under unstable conditions. The electronic structure has been calculated for elementary ZnO clusters of different symmetries by the molecular dynamics method to reveal the processes of symmetry transformations occurring under nonequilibrium conditions during the forming of the tetrapod nucleus.
