Outline of Final Research Achievements |
The purpose of this study is to resolve the optical properties of (Al,In,Ga)N-based semiconductors utilizing spectroscopy under various perturbation fields such as light, stress, electric field, and magnetic field. We therefore constructed some novel spectroscopic systems, where we can apply the perturbation field. Utilizing these kinds of spectroscopy, we demonstrated the relaxation/recombination dynamics of green-emitting InGaN and deep-ultraviolet-emitting AlGaN quantum wells, and proposed the novel model of the exciton fine structure of AlN.
