This study modeled bulk β-Li 3 PS 4 and 75Li 2 S-25P 2 S 5 glass systems using accurately parameterized potentials developed in our previous work. The bulk crystalline and glassy systems were arranged in one direction to form the interface and crystal growth simulations were conducted at desired temperatures. Special attention was paid to the dependence of crystal growth rates on the crystalline planes in contact with the glassy phase. Systems forming interfaces with seven possible crystal planes were created, and crystal growth simulations were performed. A new methodology was developed for classifying crystalline and glassy atoms based on the dynamic behavior of PS 4 3 -.
