Long-Wave (8 - 12 Micrometers) Quantum-Dot Infrared Photodetectors
Abstract
This is the Final Report of ARO Grant No. DAADl9-02-l-0437. It is a report on the characteristics of(InGa)As/GaAs long-wave (8-12 um) quantum-dot infrared photodetector structures. Pcak responsivities and dctectivitics were measured using a calibrated black body source. The results of this work indicate that for the structures characterized here, the maximum operating temperature is limited to %O5 K. No effort was made in the original design of the device structure for higher temperature operation. For operation at temperatures higher than this, one must investigate other device structures; such structures have been identified and will be the subject of future work. The work reported here has paved the way to the identification of candidate device structures for high operating temperature (HOT) quantum-dot detector
