Abstract
Using a kinetic Monte Carlo method, we simulate binary film (A0.5B0.5/A)(A0.5B0.5/A) growth on an L×LL×L square lattice with the focus on the domain growth behaviour. We compute the average domain area, A(t)A(t), as a measure of domain size. For a sufficiently large system, we find that A(t)A(t) grows with a power law in time with A(t)∼t2/3A(t)∼t2/3 after the initial transient time. This implies that the dynamic exponent for domain growth with non-conserved order parameter is z=3z=3, a value which was theoretically predicted for the conserved order parameter case. Further analysis reveals that such a power-law behaviour emerges because the order parameter is approximately conserved after the early stage of growth.
