The migration energy barrier (MEB) is a defined quantity between the equilibrium configuration and the saddle point along the migration path, which can be obtained from first-principles calculations. The knowledge about migration of point defects helps to realize their incorporation during the growth process, impurity diffusion, and modeling self-diffusion. CD ComputaBio offers migration barrier energy calculation service to serve your scientific research.
