Paper Abstract

We present results on p-type quantum well IR photodetectors (QWIPs) based on GaAs substrates, and discuss issues related to the optimization of their performance. Due to the fact that a p-QWIP allows normal incidence absorption, the simplicity in device fabrication makes it interesting for implementing a pixel-less imaging device based on the integration of QWIP and light emitting diode.
