The impact of the Bi surfactant layer on the growth of InxGa1-xAs/GaAs heterostructures by molecular beam epitaxy was examined by atomic force microscopy, reflection high energy electron diffraction, X-ray diffraction analysis, and photoluminescence spectroscopy. Results showed that Bi improves the structural and optical quality of InGaAs/GaAs structures by reducing the interfacial roughness and broadening, and by producing more intense photoluminescence peaks than those of heterostructures grown without Bi.
