Abstract:

Fundamental research issues and novel designs of Sb-based superlattice photodetectors are reported. These include the following Accomplishment 1. Growth of new InAsGaSb type-II superlattice material using MOCVD. We report the improved SL quality based on different interfacial layers IF and detector results using new growth schemes. Accomplishment 2. Demonstration of the first MOCVD grown InAsGaSb type-II superlattice photodiodes. We have characterized the photodiodes I-V curve, responsivity, and detectivity with improved performance. Accomplishment 3. Realization of the first InAsInAsSb type-II superlattice structure grown by MOCVD. We have measured the structures absorption spectra.
