Correlation between performance and compositional grading in quantum well of deep UV-LED
Abstract
Novel Aluminium compositional grading in QW has been studied in case of AlGaN based deep UV LED structure. Tailoring of electron wave-function concept has been proposed. Control and tunability of optical and the electrical output has been reported. Excellent control over carrier confinement has been proposed. The proposed structure provides excellent frame work for further research in this area.
