2.86 µm room-temperature light emission of InGaAsN/GaAsSb type-II quantum well diodes grown on InP substrates

Room-temperature light emission at a wavelength of 2.86 µm was observed for In0.53Ga0.47As0.99N0.01/GaAs0.5Sb0.5 type-II quantum well (QW) diodes grown on InP substrates by molecular beam epitaxy (MBE), which is much longer than that (2.34 µm) for In0.53Ga0.47As/GaAs0.5Sb0.5 type-II QW diodes on InP substrates. The temperature dependence of the electroluminescence (EL) spectrum indicates that the EL peak energy difference between these two diodes is 100 meV at all temperatures.
