New metastable behavior of deep levels is found in hydrogenated GaAs doped with Si. A deep level at 0.60 eV below the conduction-band minimum (Ec) is generated during hydrogenation and shows metastable for the Ec − 0.42 eV trap. From the defect transformations observed in biased anneals, these defects are found to be metastable defects associated with hydrogen atoms. Especially, the 400 K biased-anneal experiments indicate that an Ec−0.33 eV trap could be an electric field induced defect, transformed from other intrinsic defects. The Ec − 0.60 eV trap in hydrogenated GaAs could be a hydrogen complex associated with Ec − 0.42 eV trap and the hydrogen atom plays an important role in a metastability of deep level defects in GaAs.
