Radiation Effects on Space-Based Optoelectronic Materials and Devices

Abstract : We have investigated the irradiation effects on interband and intersubband transitions in III-V semiconductors quantum wells and superlattices. We also investigated irradiation induced defects in III-nitride thin films including C-H complexes in AlGaN. In particular, we investigated the Gamma-ray, electron, neutron, He(+)-ion, and proton irradiation effects on the intersubband transitions in multiple quantum wells. Thermal annealing recovery of the intersubband transition (or thermal recycling) in heavily irradiated samples has been investigated. The final report contains detail discussions of the results obtained during the last three years. At the end of the report, we listed our professional activities including technical papers, books, symposia, invited talks, and students supported by the grant.
