Vicinal surface diffusion





3D-lattice kinetic Monte Carlo simulation

perspective view of a (100) vicinal surface (f.c.c. lattice without reconstruction)

conserved-order-parameter Ising model with nearest neighbor (NN) interaction J_NN

f.c.c. lattice (12 NNs; J_NN/kT_c = 0.40837)

here: J_NN/kT = 2.5

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

time is measured in Monte Carlo steps (MCS)
