Resumo
Transient decay of persistent photoconductivity measurements are carried out in samples of different compositions. The capture barrier for electron trapping by DX centers is obtained using a method which employs the Brooks-Herring equation for the electronic mobility. The effect of polarization of the screening cloud is analysed using Takimoto's potential and specifies the limits of applicability of the Brooks-Herring equation in AlxGa1-xAs.
