Observation of Metastable and Stable Energy Levels of EL2 in Semi-insulating GaAs

arXiv:cond-mat/0503613 · doi:10.1063/1.2150579

Abstract

By using combination of detailed experimental studies, we identify the metastable and stable energy levels of EL2 in semi-insulating GaAs. These results are discussed in the light of the recently proposed models for stable and metastable configurations of EL2 in GaAs.
