One-dimensional crystal growth model on a square lattice substrate

• A one-dimensional crystal growth model along the preferential growth direction is established successfully.
• A new growth mechanism of one-dimensional crystals on isotropic substrates is shown.
• All the simulation results are in good agreement with the experimental findings.

A one-dimensional crystal growth model along the preferential growth direction is established. The simulation model is performed on a square lattice substrate. First, particles are deposited homogeneously and, as a result, each of the lattice sites is occupied by one particle. In the subsequent stage, N nuclei are selected randomly on the substrate, then the growth process starts by adsorbing the surrounding particles along the preferential growth directions of the crystals. Finally, various one-dimensional crystals with different length and width form. The simulation results are in good agreement with the experimental findings.
