Self-consistent effective-mass theory for intralayer screening in graphite intercalation compounds

DiVincenzo, D. P., Mele, E. J.·1984·Physical Review B

Abstract

The effective-mass-approximation differential equations appropriate for impurities in a graphite host are constructed and are used to solve self-consistently for the screening response surrounding a single intercalant atom. The screening cloud is found to have a very slow algebraic decay with a characteristic length of 3.8 \AA{} in the case studied. This rather long length is due to both the semimetallic and the two-dimensional character of graphite. A Thomas-Fermi description of screening is found to be adequate, but a linear-response theory is not. From these results we conclude that the transferred charge in alkali-metal---graphite intercalation compounds is distributed nearly homogeneously on a carbon plane. We discuss recent theoretical and experimental work in light of these results.

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.
