| 中文摘要 | Using a YAG:Nd laser as a pump source, the properties of electroabsorption in Stark geometry AlGaAs/GaAs multiple-quantum-well a photorefractive structure are studied at low temperature. When the temperature decreases from 160 to 120 K, the electroabsorption demonstrates the characteristics of both quenchable and unquenchable components. The quenchable component is interpreted as the photoquenching of EL2, and the unquenchable component is ascribed to the existence of additional deep levels. Modulated with an equivalent circuit, the concentrations of these defects an predicted on the order of 1.3 x 10(16) and 2.2 X 10(18) cm(-3), and the capture cross section of additional deep levels is about 4.5 X 10(-16) cm(2). The investigation of optical transient current spectra verifies our deduction. (C) 2000 American Institute of Physics. [S0003-6951(00)02931-4]. |
