Fig. 3From: Interface Intermixing in Type II InAs/GaInAsSb Quantum Wells Designed for Active Regions of Mid-Infrared-Emitting Interband Cascade LasersHAADF-STEM images for samples A and B. Blue circles represent points taken to EDX analysis. All the samples were prepared following a <110> zone axis (note: the zone axis is the direction normal to the image). EDX profiles are along the <001> direction (the growth axis). This means that the <−110> direction is along the interfacesBack to article page
