Pseudopotential calculation of the excitonic fine structure of million-atom self-assembledIn1−xGaxAs/GaAsquantum dots

Bester, Gabriel, Nair, Selvakumar, Zunger, Alex·2003·Physical Review B

Abstract

The atomistic pseudopotential method is used to accurately predict the electron-hole exchange-induced fine structure (FS) and polarization anisotropy in million-atom ${\mathrm{In}}_{1\ensuremath{-}x}{\mathrm{Ga}}_{x}\mathrm{A}\mathrm{s}/\mathrm{G}\mathrm{a}\mathrm{A}\mathrm{s}$ quantum dots of various shapes and compositions. The origin of the FS splittings is clarified using a simple model where the effects of atomistic symmetry and spin-orbit interaction are separately evident. Remarkably, polarization anisotropy and FS splittings are shown to occur, even in a cylindrically symmetric dot. Furthermore, ``dark excitons'' are predicted to be partially allowed. Trends in splittings among different shapes and compositions are revealed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
