| Outline of Final Research Achievements |
The aims of this study are to realize high-efficiency nitride-based blue LEDs, to demonstrate high-speed optical modulation by an external oscillator, and to demonstrate high-sensitivity HFET type photosensors. A blue LED with light extraction efficiency of 70 % has been achieved by applying the moth-eye-patterned sapphire substrate. Light modulation by an external modulator with Kerr effect in PLZT thin film has been confirmed by FDTD simulation, and deposition condition for the perovskite-phase PLZT thin film was fixed. Super sensitive HFET-type photosensors, whose sensitivity is four orders of magnitude higher than conventional pin photodiode, are also realized.
