Abstract

Transient decay of persistent photoconductivity (TDPPC) is employed to assess the donor- or acceptor-like nature of the DX defect in AlGaAs. The TDPPC data is analyzed in terms of the non-equilibrium capture kinetics of DX and a variation in the mobility due to ionized impurity scattering as calculated by the Brooks-Herring equation. TDPPC measurements show DX to be donorlike.
