Influence of illumination intensity on negative photoconductivity of Si ion-implanted GaAs: Cr

Negative photoconductivity (PC) was observed in Si ion-implanted GaAs:Cr below the fundamental band gap. The dependence of this effect on wavelength and intensity of illumination is reported. For photon energies slightly smaller than the optical energy gap the negative PC reverts into positive PC wi...
