2-particle sintering





3D-lattice kinetic Monte Carlo simulation

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

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

here: J_NN/kT = 1.5 (for all particles; no evaporation into the gas phase)

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

color key (right): initial affiliation

number of atoms: 56471 (particle left) + 56470 (particle right)

initial particle radius = 30 a

f.c.c. metals: Cu (a = 0.1801 nm), Au (a = 0.2039 nm), Ag (a = 0.2043 nm)

two <001>-directions are parallel to the edges of the screen; one is perpendicular to the screen

time is measured in Monte Carlo steps (MCS)
