| Abstract(in English) | Schottky-type light-emitting diodes (ST-LEDs) were fabricated using GaN layer grown on (0001) sapphire substrates by metal-organic vapor phase epitaxy (MOVPE). The near-bandegde emission (NBE) of GaN was observed from ST-LEDs with reverse bias and pulsed voltage condition. The spectra were detected from the sapphire-substrate side. Photoluminescence spectra of GaN layers were observed at the temperature from room temperature (RT) to 500K. The peak energy of NBE is shifted towards lower energy side as increasing the observed temperature. The heat generation in ST-LEDs was considered. ST-LEDs using the bandgap narrowing by the heat generation is proposed and their advantageous for integration is discussed. |
