Charge Transfer Chemical Doping of Few Layer Graphenes: Charge Distribution and Band Gap Formation
Abstract
The properties of few layer (one layer (1 L) to four layer (4 L)) graphenes doped by adsorption and intercalation of Br(2) and I(2) vapors are investigated. The Raman spectra of the graphene G vibrations are observed as a function of the number of layers. There is no evidence for chemical reaction disrupting the basal plane pi electron conjugation. Adsorption of bromine on 1 L graphene creates a high doped hole density, well beyond that achieved by electrical gating with an ionic polymer electrolyte. In addition, the 2D Raman band is completely quenched. The 2 L bilayer spectra indicate that the doping by adsorbed I(2) and Br(2) is symmetrical on the top and bottom layers. Br(2) intercalates into 3 L and 4 L graphenes. The combination of both surface and interior doping with Br(2) in 3 L and 4 L creates a relatively constant doping level per layer. In contrast, the G spectra of 3 L and 4 L with surface adsorbed I(2) indicate that the hole doping density is larger on the surface layers than on the interior layers and that I(2) does not intercalate into 3 L and 4 L. This adsorption-induced potential difference between surface and interior layers implies that a band gap opens in the bilayer type bands of 3 L and 4 L.

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.
