Direct-Bandgap InAs Quantum-Dots Have Long-Range Electron−Hole Exchange whereas Indirect Gap Si Dots Have Short-Range Exchange
TL;DR: It is shown here that in direct-gap quantum dots (such as InAs) the e-h exchange interaction is dominated by the long-range component, whereas in indirect-gapquantum dots ( such as Si) only the short- range component survives.
Journal ArticleDOI
Evaluating and improving the cluster variation method entropy functional for Ising alloys
TL;DR: It is shown that the CVM produces correlation functions that are too close to zero, which leads to an overestimation of the exact energy, E, and at the same time, to an underestimation of −TS, so the free energy F=E−TS is more accurate than either of its parts.
Journal ArticleDOI
Influence of the atomic-scale structure on the exciton fine-structure splitting in InGaAs and GaAs quantum dots in a vertical electric field
TL;DR: In this paper, the vertical electric field tuning of the exciton fine-structure splitting (FSS) in several InGaAs and GaAs quantum dots (QDs) using the atomistic empirical pseudopotential approach and configuration interaction was investigated.
Journal ArticleDOI
Calculation of the electronic properties of Mo in a first-principles nonlocal-pseudopotential approach
TL;DR: The first principles of nonlocal atomic pseudopotentials derived from the density-functional formalism were applied in a self-consistent study of the electronic properties of bulk Mo..
Journal ArticleDOI
Magnitude and Size Scaling of Intervalley Coupling in Semiconductor Alloys and Superlattices
Lin-Wang Wang,Alex Zunger +1 more
TL;DR: In this article, the authors investigate the symmetry, magnitude, and size scaling of intervalley coupling in semiconductor superlattices and alloys by direct supercell calculations, performed with screened pseudopotentials and a plane-wave basis, considering up to ${10}^{6}$ atoms/supercell.
