Abstract
We propose a theoretical approach to the general problem of phonon-coupling between localised electronic states in semiconductors, which takes advantage of results from first-principles calculations. Application of this scheme to the isolated antisite defect As(Ga) in GaAs reveals that electron-phonon coupling can provide the mechanism for the metastable transition characteristic of EL2.
