Structural and optical properties of high quality InAs/GaAs short‐period superlattices grown by migration‐enhanced epitaxy

InAs/GaAs highly strained short‐period superlattices have been grown by migration‐enhanced epitaxy on InP(001) substrates. Such samples exhibit clearly improved structural and optical properties. X‐ray diffraction, scanning transmission electron microscopy, photoluminescence, and Raman scattering experiments have been performed to characterize an (InAs)4(GaAs)3 layer.
