Abstract
We present a study about the crystallization behavior of a two-dimensional particlesystem via molecular dynamics simulation. The interaction potential used hereis a modified version of the Lennard-Jones potential which has the squarelattice as the stable crystal structure at zero-pressure. The growth rate and thethermodynamic melting point are determined using a system with a free surface in thex direction. We also performed simulations of a supercooled liquid system with periodicboundary conditions to estimate the nucleation rate, the critical nucleus size, and the timelag of nucleation. These properties are important tools for understanding the crystallizationphenomenon in a variety of materials.
