Enhanced Performance of an AlGaN-Based Deep-Ultraviolet LED Having Graded Quantum Well Structure by Huabin Yu, Qian Chen, Zhongjie Ren, Meng Tian, Shibing Long, Jiangnan Dai, Changqing Chen, Haiding Sun

“…In this paper, we propose a novel DUV LED structure embedded with graded QWs in which the Al composition was linearly changed to screen the QCSE. A significant increase of the internal quantum efficiency and thus an enhancement of the light output power by nearly 67% can be achieved, attributing to the improvement of the electron-hole wave function overlap (Г_e-hh) to 58.6% in the Increased-Al-composition graded QWs, as compared to the QW without grading (Г_e-hh = 40.4%) and reverse grading (Г_e-hh = 33.6%). …”
