Wavelength stable green InGaN micro LEDs monolithically grown on silicon substrate

IMAGE: (A) SCHEMATIC OF THE INGAN/AGAN MULTIPLE-QUANTUM-WELL NANOWIRE ARRAY. (B) THE PEAK WAVELENGTH OF THE DEVICE’S ELECTROLUMINESCENCE STAYS CONSTANT OVER ONE ORDER OF MAGNITUDE OF CHANGE IN CURRENT INJECTION. (C) THE CURRENT VOLTAGE CHARACTERISTICS OF A DEVICE THAT SHOWS GOOD RECTIFICATION RATIO AND STRONG GREEN EMISSIO...
