Paper Abstract

We characterize high quantum efficiency double GaAs/InGaP heterostructures used in semiconductor laser cooling. To identify potential samples for laser cooling, measuring the nonradiative recombination rate coefficient is necessary. We describe a technique called power dependent photoluminescence measurement, which when combined with timeresolved photoluminescence lifetime determines the nonradiative recombination coefficient.
