Quantum dot materials for mid-IR photodetection: opinion

In this opinion we trace the evolution of the quantum dot mid-infrared photodetector, from epitaxially-grown self-assembled quantum dot detectors, to a new generation of colloidal nano-crystal based devices. We opine on the advantages and challenges associated with these colloidal quantum dot materials and discuss their potential for commercial device applications.
