  2. Polarization Response of Multi-layer InAs Quantum Dot Stacks

    25 Oct 2011 | Online Presentations | Contributor(s): Muhammad Usman

    Recent experimental measurements, without any theoretical guidance, showed that isotropic polarization response can be achieved by increasing the number of QD layers in a QD stack. In this work,...
