Indium-tin-oxide (ITO) films are widely applied as the transparent conductive layers in light emitting diodes and solar cells. In this paper, ITO nanowiskers have been obtained by controlling the oxygen flow in the process of evaporation by electron-beam evaporation technique. ITO nanowiskers appeared for specific vapor-liquid-solid (VLS) growth conditions in the process. Nanowisker ITO films were...
We fabricated GaN-based flip-chip light-emitting diodes (FC-LEDs), which were grown on both conventional and high purity SiC substrates. The influence of beveling, thickness, and absorption of the SiC substrate on the light extraction efficiency (LEE) of the FC-LED was investigated by simulation and experiment. From the simulation results, the LEE of the FC-SLED with a 60$^{\circ}$ beveling angle...
Total internal reflection (TIR) effect leads to low light extraction efficiency (LEE) of the GaN LEDs on SiC and sapphire substrates. The LEE enhancements of the GaN based flip-chip light-emitting diodes (FC-LEDs) on patterned substrates are investigated by experiments and simulations. The optical output power of the FC-LEDs on patterned SiC substrate increases by 8.15% while the optical output power...
