Density functional theory of heterogeneous nucleation and microstructure formation

点击翻译按钮获取中文摘要

Density functional theory of freezing will be employed as a microscopic theory for heterogeneous crystal nucleation and subsequent microstructure formation. Heterogeneous nucleation at external system boundaries and around fixed particles at prescribed positions will be determined and the subsequent growth into a solid microstructure will be calculated within dynamical density functional theory. The connection to phase field models which operate on larger length and time scales will be explored. Results will be compared to complementary approaches like computer simulations and experiments on colloidal suspensions.
