Abstract

Previously we introduced a novel fin shape light-emitting diode (LED) architecture based on sub-micron n-ZnO/p-GaN heterojunctions that at high current densities demonstrated a droop-free behavior. Efficiency droop, which is the decline in internal quantum efficiency with increasing current density, is one of the significant challenges facing wide bandgap LEDs. In the present work, we discuss performance of fins of wide band gap materials such as AlGaN that are formed on GaN. Discussion also includes electroluminescence and different types of efficiencies of these LEDs for generation of UV wavelengths as well as the significance of the fin shape in improving their performance.
