Özet

A theoretical investigation of GaAs/AlGaAs infrared detector consisting of four asymmetric quantum wells is presented. Each well is designed to yield absorption and a photoresponse at peak wavelengths of 7.9, 9.2, 10.4, and 11.8 mu m, respectively. The device operation is based on intersubband bound to bound transition. (C) 2007 Elsevier B.V. All rights reserved.
