Improvement on the luminescence efficiency, electroluminescence linewidth and transport properties of ZnCdSe/ZnCdMgSe Quantum Cascade structures

We present electroluminescence from ZnCdSe/ZnCdMgSe Quantum Cascade structures, with 3 times higher luminescence efficiency, 30% narrower electroluminescence linewidths than our first demonstration. The measured turn-on voltage matches with the calculated value.
