Comment on "Reversible disorder-order transitions in atomic crystal nucleation".

Abstract

Jeon et al. (Reports, 29 January 2021, p. 498) reported reversible fluctuations between disordered and crystalline states during nucleation. We argue that the adoption of "magic numbers" for separation of the size range into three parts is misleading when using the sigmoid functions and that their figure 3B was wrongly illustrated. The crystal shape effect was neglected during theoretical analysis.
