ABSTRACT
We investigated the influence of the growth temperature (T[sub gr]) on the microstructure and on the optical properties of GalnNAs quantum wells (QWs). By comparing the structural information (transmission electron microscopy) with the optical properties (photoluminescence spectroscopy), we demonstrate that high photoluminescence efficiency of GalnNAs QWs is achieved only when the two-dimensional growth mode is preserved, which can be obtained at a low T[sub gr] even for high In content. We also show composition modulations in the GaInNAs QWs, which can lead to the interface roughness.
