01 Apr 2012 | Online Presentations | Contributor(s): Muhammad Usman
Deployment of nanometer-sized semiconductor quantum dots (QDs) in the active region of photonic devices such as lasers, semiconductor optical amplifiers (SOA's), photo-detectors etc. for the next …
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, we …
Quantitative Modeling and Simulation of Quantum Dots
18 Apr 2011 | Notes | 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 …
