Strong surface scattering in ultrahigh-mobilityBi2Se3topological insulator crystals
Open accessAbstract
While evidence of a topologically nontrivial surface state has been identified in surface-sensitive measurements of ${\text{Bi}}_{2}{\text{Se}}_{3}$, a significant experimental concern is that no signatures have been observed in bulk transport. In a search for such states, nominally undoped single crystals of ${\text{Bi}}_{2}{\text{Se}}_{3}$ with carrier densities approaching ${10}^{16}\text{ }{\text{cm}}^{\ensuremath{-}3}$ and very high mobilities exceeding $2\text{ }{\text{m}}^{2}\text{ }{\text{V}}^{\ensuremath{-}1}\text{ }{\text{s}}^{\ensuremath{-}1}$ have been studied. A comprehensive analysis of Shubnikov-de Haas oscillations, Hall effect, and optical reflectivity indicates that the measured electrical transport can be attributed solely to bulk states, even at 50 mK at low Landau-level filling factor, and in the quantum limit. The absence of a significant surface contribution to bulk conduction demonstrates that even in very clean samples, the surface mobility is lower than that of the bulk, despite its topological protection.

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.
