摘要
We present a reliable method for determining the strain in InGaAsN quantum wells. The method uses the fact that the splitting between heavy hole and light hole energy levels depends mostly on the strain. We also found that the strain was largely relaxed in an In0.34Ga0.66As/GaAs quantum well, but recovered when a small amount of nitrogen was added to the In0.34Ga0.66As layer.
