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 JNN
  • f.c.c. lattice (12 NNs; JNN/kTc = 0.40837)
  • here: JNN/kT = 2.5
  • color key: coordination number from red (monomers) to purple (12 NNs)
  • time is measured in Monte Carlo steps (MCS)
