Polarization Response of Multi-layer InAs Quantum Dot Stacks
25 Oct 2011 | | 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, we analyse the polarization response of multi-layer quantum dot stacks containing up to nine quantum...
