Formation of a crystal nucleus from liquid

WebJul 27, 2010 · Crystallization is a process in which an ordered phase emerges from a disordered state. It is important not only as a fundamental problem of nonequilibrium statistical physics, but also as that of materials science. The initial state is a disordered liquid and the final state is a stable crystal. WebDec 1, 2024 · The liquid sample is generated by melting the crystal at 3000 K for 200 ps, relaxing at 1200 K for 30 ps, and finally quenching to 600 K with a rate of 2 × 10 13 K/s. In all the simulations, we use a time step of 3 fs and an NPT ensemble with Parrinello-Rahman barostat and Langevin thermostat.
