2f. Temperature Screening Procedure. To study the stability of nanocrystals grown in the presence of the electric field, temperature-screening simulations were performed. The electric field was instantaneously switched off after 4.2 ns of simulation, and the set point temperature for all 10 trajectories, from the crystal grown from the initially 𝛼-glycine seed, was reset to a new temperature. The velocities were reinitialized according to the new set point temperature. The resulting 𝑛 and solid glycine dipole alignment were then monitored with time in the absence of the electric field. The initially 𝛼-glycine seed system was selected for temperature screening analysis, as the crystal size produced from this system was smaller at the end of the 4.2 ns of 0.6 V/nm electric field simulation than the crystal produced by either 𝛽-, or 𝛾-glycine. As the stability of a nanocrystal decreases with decreasing size due to an increased surface area to volume ratio, the crystal produced from 𝛼-glycine provided the hardest test case to prevent solid-state conversion of the new form to 𝛼-, 𝛽-, or 𝛾-glycine.
