Cover Story: A new atomistic mechanism of heterogeneous nucleation is established, based on molecular dynamics simulations of liquid/substrate with negative lattice misfit. We found that nucleation completes deterministically within three atomic layers by structural templating to form a two-dimensional nucleus from which the new phase can grow: (1) The first layer accommodates misfit through a partial edge dislocation network; (2) the second layer twists an angle through a partial screw dislocation network to reduce lattice distortion; (3) the third layer creates a crystal plane of the solid (the 2D nucleus). This finding opens a new door to understand heterogeneous nucleation at atomic level. View this paper
