Ostwald Ripening (coarsening)3D Lattice Kinetic Monte Carlo Simulation

solubility scales with curvature (analogous to the Gibbs-Thomson equation); large particles grow at the expense of smaller ones (particle coarsening)

original paper: W. Ostwald, Z. Phys. Chem. 34(1900) 495.

atomic dynamics is based on the conserved-order-parameter Ising model with nearest neighbor (NN) interaction J _{NN}

f.c.c. lattice (12NNs; J _{NN}/kT_{c}= 0.40837)

here: J _{NN}/kT = 1.3; N_{atoms}= 7128; R_{i}= 12a (both clusters)

color key: coordination number from pink (monomers) to purple (12NNs)

time is measured in Monte Carlo steps (MCS)

simulation cell: (128a x 128a x 128a) with periodic boundaries
