Extended Data Fig. 3: Comparison of the crystallization process with a flat wall and in bulk in simulations at various T (κσ ~ 2.0).

a, The solid fraction versus the time t for samples with a flat wall. We observe a fast wall-assisted crystallization until the growth front meets the small crystal nucleus caused by spinodal nucleation inside the sample (see inset figure). b, The solid fraction versus the time t for bulk samples. The crystallization speed is much lower than in a, which is approximately indicated by the dashed line.
