Conference paper


A luminescence study of In1-xGaxAs1-yPy has been performed to determine the electronic hand structure of this quarternary alloy. Electron microprobe cathodoluminescence at 300 K was used to determine the direct Γ8vlc gap and photoluminescence at 2 K for the indirect Γ8v-Xlc gap. Comparison of the experimentally determined gaps is made with the theory of Van Vechten and Bergstresser and with a simple interpolation procedure employing the experimentally determined gaps of the ternary alloy systems which constitute the boundaries of this quaternary.
