A kinetic model for nanocrystal morphology evolution.
A kinetic model is developed with the goal of understanding and predicting the morphology evolution of nanocrystals in nonequilibrium growth conditions. The model is based on the assumption that under such conditions, different crystal planes have different kinetic parameters. This model focuses on the morphology-developing stage and is successfully related to the nucleation process and other crystal evolution mechanisms. It is believed to be a universal model and is applied to discuss the morphology evolution of CdSe nanocrystals, including the aspect ratio, injection schemes, ligands effect and morphology distribution.
