Journal ArticleDOI
Wide InP nanowires with wurtzite/zincblende superlattice segments are type-II whereas narrower nanowires become type-I: an atomistic pseudopotential calculation.
TL;DR: It is shown via InP nanowires that as the nanowire diameter decreases, quantum-confinement alters this basic material property, placing both electrons and holes on the same (ZB) phase.
Journal ArticleDOI
Direct observation of the structure of band-edge biexcitons in colloidal semiconductor CdSe quantum dots
TL;DR: In this article, the electronic structure of the band-edge biexciton in colloidal CdSe quantum dots using femtosecond spectroscopy and atomistic many-body pseudopotential calculations was reported.
Journal ArticleDOI
Correlation versus mean-field contributions to excitons, multiexcitons, and charging energies in semiconductor quantum dots
TL;DR: In this paper, the physical content of these energies can be calculated via quantum Monte Carlo (QMC) and configuration interaction (CI) methods, which can be used to resolve the energies of excitons, multiexcitons and charging of semiconductor quantum dots.
Journal ArticleDOI
Pseudopotential study of electron-hole excitations in colloidal free-standing InAs quantum dots
Andrew Williamson,Alex Zunger +1 more
TL;DR: In this article, an analysis of the single particle states involved in each excitation in terms of their angular momenta and Bloch-wave parentage was performed for free-standing, surface passivated, InAs quantum dots using atomic pseudopotentials for the singleparticle states and screened Coulomb interactions for the two-body terms.
Journal ArticleDOI
Fingerprints of CuPt ordering in III-V semiconductor alloys: Valence-band splittings, band-gap reduction, and x-ray structure factors
Su-Huai Wei,Alex Zunger +1 more
TL;DR: In this paper, the local density approximation (LDA)-corrected formalism was used to calculate the band-gap reduction and spin-orbit splitting for ordered alloys, and the x-ray structure factors for these materials as a function of the degree of long range order.
