TL;DR: In this article, self-assembled InAs-InGaAs-GaAs quantum dots are exploited for the development of large-format long-wavelength infrared focal plane arrays (FPAs).
Journal ArticleDOI
Quantum Dot Based Infrared Focal Plane Arrays
TL;DR: The progress from the first raster scanned image obtained with a QD detector to the demonstration of a 640 512 imager based on self-assembled quantum dots (QDs) is reviewed and emphasis will be placed on a novel quantum dots-in-a-well (DWELL) design, which represents a hybrid between a conventional quantum-well infrared photodetector (QWIP) and a quantum-dot infrared photodiode (QDIP).
Journal ArticleDOI
