Enhancing Carriers’ Confinement by Introducing BAlGaN Quantum Barriers for the Better Optoelectronic Performance of Deep UV LEDs by Jamshad Bashir, Muhammad Usman, Dmitri Sergeevich Arteev, Zoya Noor, Ahmed Ali

“…Keeping this in mind, we have improved the carriers’ confinement by introducing a small amount of Boron nitride (BN) (2%) in ternary QBs and an electron injecting layer, which results in higher barriers that restrict the out-of-active region movement of electrons and holes. With quaternary B_xAl_yGa_zN QBs, significantly enhanced electrons and hole concentrations can be observed in the active region of quantum wells (QWs), which leads to a 4.3 times increased radiative recombination rate with a 68% better internal quantum efficiency (IQE) than the referenced conventional LEDs. …”
