Collaborative Research and Development (CR&D). Delivery Order 0069: Photoluminescence Investigations on Semiconducting Quantum Dots Quantum Wells and Thin Films

摘要

This research in support of the Air Force Research Laboratory Materials and Manufacturing Directorate was conducted at Wright-Patterson AFB, Ohio from 27 February 2007 through 22 July 2007. The task of the project focused on photoluminescence (PL) experiments on various semiconducting samples grown with Molecular Beam Epitaxy (MBE) at MLPS. Quantum structures and quantum dots composed of InAs, GaAs, and GaSb have been investigated. The structures are potential candidates for highly sensitive infrared (IR) detectors and the knowledge of their optical performance such as PL is of considerable importance for the AF and the community in general.
