Optical Properties of III-V Semiconductor Nanostructures and Quantum Wells

Abstract : We have investigated the optoelectronic applications of interband and intersubband transitions in III-V semiconductors quantum wells and quantum dots. The research efforts included the investigation of intersubband transitions in GaN/AlGaN multiple quantum wells for the 1.3 and 1.5 micron spectral ranges. These wavelengths are important for optical communications. Furthermore, we investigated single wall carbon nanotubes for possible use as space-based solar cell. 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.
