Crystal growth simulations were conducted at 500 K and 1 atm. The crystallization of β-Li 3 PS 4 within 75Li 2 S-25P 2 S 5 glass has been observed experimentally at this temperature. The equilibrated model at 300 K was heated to 500 K at a rate of 1.0 K/ps. Atomic structures during crystal growth were sampled over 30 ns in the NPT ensemble. For the (010) crystalline plane-which showed the fastest crystallization rate (as discussed in Sec. "Crystallization Dynamics")-additional simulations were performed at 300 K and 1 atm to verify the absence of crystal growth at lower temperatures.
