  • Abstract
    Differential transmission spectroscopy is used to measure carrier dynamics in a quantum-dots-in-a-well heterostructure. This provides fundamental insight into carrier relaxation from three to two to zero dimensions and has significant implications for dots-in-a-well-based mid-infrared photodetectors.
