title: Crystallization kinetics of a 2D system using molecular dynamics simulation.
abstract: We present a study about the crystallization behavior of a two-dimensional particle system via molecular dynamics simulation. The interaction potential used here is a modified version of the Lennard-Jones potential which has the square lattice as the stable crystal structure at zero-pressure. The growth rate and the thermodynamic melting point are determined using a system with a free surface in the x direction. We also performed simulations of a supercooled liquid system with periodic boundary conditions to estimate the nucleation rate, the critical nucleus size, and the time lag of nucleation. These properties are important tools for understanding the crystallization phenomenon in a variety of materials.
