20.8% Peak External Quantum Efficiency of Red (619 nm) InGaN/GaN MicroLEDs

Abstract Red-emitting indium gallium nitride (InGaN) micro-light-emitting diodes (μLEDs) remain challenging due to reduced radiative efficiency at the high indium compositions required for long-wavelength emission. Here, we demonstrate InGaN/GaN red μLEDs emitting at 619 nm that...
