  1. Comparison of PCPBT Lab and Periodic Potential Lab

    10 Aug 2009 | | Contributor(s):: Abhijeet Paul, Samarth Agarwal, Gerhard Klimeck, Junzhe Geng

    This small presentation provides information about the comparison performed for quantum wells made of GaAs and InAs in two different tools. This has been done to benchmark the results from completely two different sets of tools and validate the obtained results. In this presentation we provide...

  2. 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...

  3. Why quantum dot simulation domain must contain multi-million atoms?

    11 Jan 2013 | | Contributor(s):: Muhammad Usman

    The InGaAs quantum dots obtained from the self-assembly growth process are heavily strained. The long-range strain and piezoelectric fields significantly modifies the electronic structure of the quantum dots. This imposes a critical constraint on the minimum size of the simulation domain to...
