Extended Data Fig. 1: Layering property of interface particles.

a, Histogram of La(i) for all particles at the initial crystal growth stage. It can efficiently distinguish layered particles from unlayered particles. b, Histogram of ξ(i) for the layered particles in a. The layered particles at interface contains both the solid surface and interface liquid. c, Histogram of La(i) for solid surface particles and interface liquid particles respectively.
