Abstract
We report on preliminary muon-track-induced current measurements in semi-insulating (SI-) GaAs. At T=70K, after simultaneous treatment of the sample by muon irradiation and a strong electric field (a square wave with |E|>10kV/cm and the polarity changed every 150Â s) for approximately 2Â h, the sample is transferred to a metastable-like state which is characterized by increased life-times for non-equilibrium electrons and holes. The sample can be returned to the original state by heating up to 250Â K. Our results for SI-GaAs suggest a muon-track-induced electric-field-assisted neutralization process for the deep traps.
