Localization, hopping, and diffusion of electrons in molten salts

Selloni, A., Carnevali, P., Car, R., Parrinello, M.·1987·Physical Review Letters

Abstract

The electronic states and dynamical properties of dilute liquid K-KCl solutions are studied by simultaneous integration of the coupled time-dependent Schr\"odinger equation for the excess electrons and classical equations of motion for the ions. Excess electrons are found to spend most of their time in localized F-center states, whose size and shape can fluctuate significantly. Transport is mostly due to jumps between localized states, with a jumping rate \ensuremath{\simeq}3\ifmmode\times\else\texttimes\fi{}${10}^{12}$ ${\mathrm{s}}^{\mathrm{\ensuremath{-}}1}$. The optical excitation spectrum and the electron diffusion coefficient are calculated and found to be in agreement with the experimental data.

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.
