Phonon renormalization in doped bilayer graphene

Abstract

We report phonon renormalization in bilayer graphene as a function of doping. The Raman $G$ peak stiffens and sharpens for both electron and hole doping as a result of the nonadiabatic Kohn anomaly at the $\ensuremath{\Gamma}$ point. The bilayer has two conduction and valence subbands, with splitting dependent on the interlayer coupling. This gives a change of slope in the variation of $G$ peak position with doping which allows a direct measurement of the interlayer coupling strength.

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.
