Of the three polymorphs, 𝛾-glycine shows the fastest solid-state transition rate, where the growth of the initially 𝛾-glycine nanocrystals takes places 0.25 ns after the application of the 0.6 V/nm field. This is in contrast to the case of 𝛼and 𝛽glycine, where growth occurs 0.5 ns after the application of the 0.6 V/nm field in the case of 𝛽-, or 1 ns after the application of the 0.6 V/nm field in the case of 𝛼-glycine.
