The main research content of crystal growth dynamics is to clarify the crystal growth mechanism under different growth conditions, and the relationship between crystal growth rate and growth driving force. The crystal growth rate is governed by the growth driving force. When the heat or mass transport of the growth medium is changed, the crystal growth rate also changes. The structure of the crystal growth interface determines the growth mechanism, and different growth mechanisms show different growth dynamics. The morphology of crystal growth depends on the relative growth rates of the various crystal faces of the crystal, so the transport and other dynamic processes that affect the growth rate will also affect the morphology of crystal growth.
