Persistent Decrease of Dark Conductivity due to Illumination in AlGaAs/GaAs Modulation-Doped Heterostructures

We report on a persistent decrease of the dark conductivity in AlGaAs/GaAs heterostructures due to illumination. The decrease was observed for photon energies between 0.7 and 1.15 eV and larger than 1.4 eV in the temperature range 170
