Compositional dependence of the electron effective mass in the GaNAs alloy. The red dots represent experimentally determined values in GaNAs/GaAs QWs via the ODCR measurements [49]. The open triangles represent the values indirectly deduced by analyzing the quantum confinement energies in the GaNAs/GaAs QWs, from Ref. [51]. The solid blue lines show predictions based on the BA model [53]. The dashed green lines represent the results of the k·p calculations [39].
