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...
Quantitative Modeling and Simulation of Quantum Dots
18 Apr 2011 | | Contributor(s):: Muhammad Usman
Quantum dots grown by self-assembly process are typically constructed by 50,000 to 5,000,000 structural atoms which confine a small, countable number of extra electrons or holes in a space that is comparable in size to the electron wavelength. Under such conditions quantum dots can be...
