| Outline of Final Research Achievements |
To improve internal quantum efficiency of AlGaN-based Deep UV (DUV) LED's, two step sublimation growth process of bulk AlN has been established. Ex situ annealing was found to be very effective to improve crystalline quality of very thin AlN on a sapphire substrate. Direct growth of transparent graphene on p-GaN was succeeded. Also control of carbon nanotube electrode was successfully conducted, thereby reducing the operation voltage. Polarization doping was found to be very effective to reduce operating voltage. As a result, high power DUV was commercialized and applied as a light source in a water purification system.
