The left panel illustrates a conventional DWELL structure where a SK QD, consisting of pyramidal shape QD resting on a wetting layer, is embedded in a QW structure. The right panel show two stacks of SML QDs embedded in a QW.
Measured normal and 45° incidence spectral responsivity curves for two SML QDIP samples.
Dark current limited and background (300 K, optics) limited specific detectivity as a function of operating temperature for two SML QDIP samples.
