Very Long Wavelength InxGal . xAs / GaAs Quantum Well Infrared Photodetectors

چکیده
We demonstrate the first long-wavelength (Xc= 20 pm) quantum WN infrared photodetector using non-lattice matched InxGaj-xAs/GaAs materials system. High optical gains (low capture probabilities) were achieved by using GaAs as a barrier material in this system. The dctcctivity has been found to be comparable to those achieved with the usual lattice matched GaAs/AlxGal-XAS detectors.

In this paper, we discuss the development of very sensitive very long wavelength infrared (VWIR) GaAs/AIXGal.XAs quantum well infrared photodetectors (QWIPS), fabrication of random reflectors for efficient light coupling, and the demonstration of a V WIR 128 x 128 focal plane array imaging camera. Excellent imagery, with a noise equivalent differential temperature (NEAT) of 30 mK has been achie...

As a potential candidate for mid-infrared ~3–5 mm! and far-infrared ~8–14 mm! photon detection, the quantum dot infrared photodetector ~QDIP! has been the subject of extensive research efforts in recent years. Normal-incidence QDIPs with n-n-n and n-i-n vertical configurations have been reported. Compared with quantum well infrared photodetectors, QDIPs are sensitive to normal-incidence infrare...

The responsivity to long wavelength ~513 and 1253 mm! far-infrared ~FIR! radiation and the root mean square noise voltage has been measured for one bulk GaAs and two GaAs/AlGaAs multiquantum-well ~MQW! hot-electron photodetectors as a function of temperature from 4.49 to 77 K. From these data the noise-equivalent power ~NEP! was determined for each device over the same temperature range. The MQ...
