Résumé

EL2 and DX centers have been studied by positron annihilation. A vacancy defect is observed in the metastable state of EL2. The vacancy has a smaller open volume than isolated As and Ga vacancies and its charge is negative. A vacancy with metastable properties is also observed in the deep ground state of the DX center. The results are in good agreement with the vacancy interstitial model for the structure of the EL2 and DX centers.
