Abstract

We present the results of the space charge spectroscopy of integrated quantum well infrared photodetector - light emitting diode (QWIP-LED). Quasistatic capacitance-voltage (C-V) characteristics under reverse bias display a steplike behavior due to a step-wise extension of the space charge region with bias. The parameters of the steps, and the frequency dispersion of the capacitance are used to determine the QW period thickness. QW doping level,and the number of QW periods. Measurement of the QWIP-LED admittance at various temperatures is used to obtain the QW activation energy and the conduction band offset. (C) 2001 Elsevier Science B.V. All rights reserved.
