For “AlInN/GaN MQW UV-LEDs”.

Among III-Nitride semiconductors, the AlInN can only be grown lattice-matched to GaN. The lattice-matched AlInN/GaN structure should be free from cracks and strain-driven defects, which limit the performance of UV/Visible LEDs and LDs using conventional lattice-mismatched AlGaN/GaN and InGaN/GaN structures. In addition, the AlInN/GaN structure has a larger bandgap discontinuity and a larger refractive index contrast, which more strongly confine the injected carriers in the quantum wells and the emitted light in the active region. Thus, the AlInN/GaN structures are expected not only to improve the device properties but also to increase the design flexibility for novel III-nitride devices. Here we report the achievement of p-type doping in AlInN and describe AlInN-based light-emitting devices.
