Point defect 3- Edge dislocation rate constants and bias factors using lattice relaxation and monte carlo simulations

The rate constant for the vacancy-edge dislocation interaction is obtained using Monte Carlo simulations with the drift field obtained from lattice relaxation simulations. The effective trapping radius, which is obtained as a function of temperature and dislocation density, appears to be ∼3.4 times the value obtained using standard techniques. Also Monte Carlo simulations are performed for the self-interstitial dislocation interaction using a simple binding field. As a final result the bias factor is obtained as a function of dislocation density and temperature.
