We have employed Lattice Kinetic Monte Carlo (LKMC) technique to understand the kinetics of formation, as well as the spatial and size distributions of oxide nanoclusters in bcc Fe . The basic energy parameters for the LKMC were obtained from ab initio calculations. At 1050 K, we observed formation of ~ 2 nm nanoclusters highly enriched with Y and O . Ti is found to refine the size of nanoclusters, which is in accord with available experimental results.

In this paper we discuss possible mechanisms of PV annealing in Si. Our approach includes a combination of density functional theory and lattice kinetic Monte-Carlo (LKMC) simulations. The density functional theory is used to find the binding energies and jump barriers for P-V pair at different separations (from one to three interatomic bonds between complex constituents) and in different charge states. The mobility of the complex is simulated by LKMC with event probabilities calculated based on the energies from ab-initio calculations. .

We present an ab initio study of surface supported Au–Mn nanowires. Three different substrates are discussed: Cu(110), stepped Cu(111) and Si(001) surface. The emergence of stable antiferromagnetic (AFM) solutions in Au–Mn nanowires was found in all three cases. We found the nonzero magnetic moments of Mn atoms, however, the bulk of manganese is paramagnetic. The critical temperature of the Au–Mn wires is calculated by means of kinetic Monte Carlo simulation. The strong size-effect of the critical temperature is demonstrated.
