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

    04 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...

  8. Excited State Spectroscopy of a Quantum Dot Molecule

    16 Dec 2011 | | Contributor(s):: Muhammad Usman

    Atomistic electronic structure calculations are performed to study the coherent inter-dot couplings of the electronic states in a single InGaAs quantum dot molecule. The experimentally observed excitonic spectrum by Krenner et al (Phys. Rev. Lett. 94 057402, 2005) is quantitatively reproduced,...
