Highly efficient AlGaN-based deep-ultraviolet light-emitting diodes: from bandgap engineering to device craft
{{output}}
AlGaN-based light-emitting diodes (LEDs) operating in the deep-ultraviolet (DUV) spectral range (210-280 nm) have demonstrated potential applications in physical sterilization. However, the poor external quantum efficiency (EQE) hinders further advances in the... ...
