Shell-Tunneling Spectroscopy of the Single-Particle Energy Levels of Insulating Quantum Dots
Epam Erik Bakkers,Z Hens,Alex Zunger,A. Franceschetti,Leo P. Kouwenhoven,Leonid Gurevich,Daniel Vanmaekelbergh +6 more
TL;DR: In this paper, the energy levels of CdSe quantum dots are studied by scanning tunneling spectroscopy, where the tip-dot distance of the quantum dot can be varying to switch from shell-filling to shell-tunneling.
Journal ArticleDOI
Al on GaAs(110) interface: Possibility of adatom cluster formation
TL;DR: In this paper, a reexamination of the experimental data and previous electronic-structure calculations on the prototype Schottky system Al/GaAs(110), together with new calculations, indicates that at low coverages and temperatures neither a covalent bond nor a metallic bond is likely to be formed between Al and the substrate.
Journal ArticleDOI
Lifetime and polarization of the radiative decay of excitons, biexcitons, and trions in CdSe nanocrystal quantum dots
TL;DR: In this paper, a pseudopotential configuration-interaction method was used to calculate the intrinsic lifetime and polarization of the radiative decay of single excitons, positive and negative trions, and biexcitons in CdSe nanocrystal quantum dots.
Journal ArticleDOI
Confinement, surface, and chemisorption effects on the optical properties of Si quantum wires
TL;DR: The calculated energy dependence of the transition lifetimes is too strong to explain the observed low-energy slow emission band in porous Si purely in terms of transitions in an ideal wire, however, an alternative model, which introduces a mixture of wires and boxes, can account for the experimental slope.
Journal ArticleDOI
Effects of interfacial atomic segregation and intermixing on the electronic properties of InAs/GaSb superlattices
Rita Magri,Alex Zunger +1 more
TL;DR: In this paper, the effect of interfacial atomic mixing on the electronic structure of InAs/GaSb superlattices, including electron and hole energies and wave function localization, interband transition energies, and dipole matrix elements, was studied.
