We theoretically calculated the light extraction efficiency of the light-emitting diodes (LEDs) with a moth-eye structure by rigorous coupled wave analysis (RCWA). The dependences of light extraction efficiency on aspect ratio and period were measure

High-quality ( 1 1 2 ¯ 0 ) GaN layers with atomically flat surface have been grown on a precisely offset-angle-controlled ( 1 1 ¯ 0 2 ) sapphire substrate by metal-organic vapor phase epitaxy (MOVPE). Insertion of AlGaN layer between underlying AlN

We have demonstrated a UV-laser diode with a lasing wavelength of 350.9 nm, which has a GaN-AlGaN multiquantum-well (MQW) active layer and was grown on low-dislocation-density Al/sub 0.18/Ga/sub 0.82/N template. The Al/sub 0.18/Ga/sub 0.82/N template

The combination of a low-temperature-deposited AlN interlayer technology and lateral seeding epitaxy (Hetero-ELO) yielded crack-free and low-dislocation-density AlGaN. The AlGaN over the grooves has a dislocation density as low as 2 × 107 cm–2 due

To realize high-performance UV-light-emitting diodes (UV-LEDs), thick, crack-free and high-crystalline-quality AlGaN films with a low threading dislocation density and a device structure without any absorbing layer such as GaN are essential. Crack-fr

We have developed GaN/AlGaN multi-quantum-well (MQW) UV-laser diode (UV-LD) grown on sapphire substrate. The combination of a low-temperature-deposited AlN interlayer technology and lateral seeding epitaxy yielded crack-free and low-dislocation-densi
