| Abstract(in English) | AlGaN light-emitting diodes (LEDs) have been extensively studied for highly efficient light sources in deep ultraviolet (UV) range. One of the central issues in deep UV LEDs is their low light extraction efficiency. A p-GaN contacting layer, which is widely used for blue-UV LEDs, absorbs the emitted light in deep-UV LEDs. As a result, it is difficult to extract the light from the surface, and the efficiency of the light extraction is limited up to 50%. Therefore, it is very important to develop a transparent p-AlGaN contacting layer in AlGaN LEDs. Here we report the fabrication of the LED containing a p-Al_<0.7>Ga_<0.3>N contacting layer. Nearly zero absorption in the p-contacting layer increased the light extraction efficiency with a reflective metal electrode. |
