Kinetic Monte Carlo simulations: an accurate bridge between ab initio calculations and standard process experimental data

Kinetic Monte Carlo (KMC) atomistic process simulations mimic the jumps and interactions of individual atoms, based on jump rates derived from ab init io calculations or experiments. By only following 'defect' atoms (unlike mo lecular dynamics), KMC can simulate the typical long annealing times (secon ds to hours) used in materials processing. Thus, it provides a detailed and accurate link between parameters obtained from ab initio calculations and experiments performed under typical processing conditions. We describe the simulation scheme and discuss some of the unique features of this simulatio n technique with the help of results obtained with it. (C) 2000 Elsevier Sc ience Ltd. All rights reserved.
