Abstract : The objective of this project is to perform theoretical and experimental studies of dark current, photocurrent, optical absorption, spectral responsivity, noise, and detectivity for the normal incidence strained layer p-type III-V semiconductor quantum well infrared photodetectors (QWIPs) developed under this program. The material systems under investigation include InGaAs/InAlAs on InP substrates and GaAs/InGaAs or AlGaAs/InGaAs on GaAs substrates. The project will study the usage and effects of biaxial tension and compressional strain on the material systems and their effects towards photodetector design. jg
