Abstract
Simultaneous near-field fluorescence lifetime imaging and atomic force microscopy identify radiative, interface and subsurface defect recombination sites in GaAs/GaInP heterostructures. Such unique characterization plays a significant role in identifying candidate samples for laser cooling.
