High-field Shubnikov–de Haas oscillations in the topological insulator Bi2Te2Se
Open accessAbstract
We report measurements of the surface Shubnikov--de Haas oscillations (SdH) on crystals of the topological insulator Bi${}_{2}$Te${}_{2}$Se. In crystals with large bulk resistivity ($\ensuremath{\sim}4$ $\ensuremath{\Omega}\phantom{\rule{0.16em}{0ex}}$cm at 4 K), we observe $\ensuremath{\sim}15$ surface SdH oscillations (to the $n=1$ Landau level) in magnetic fields $B$ up to 45 T. Extrapolating to the limit $1/B\ensuremath{\rightarrow}0$, we confirm the $\frac{1}{2}$-shift expected from a Dirac spectrum. The results are consistent with a very small surface Land\'e $g$ factor.

Quantum relaxation time and transport relaxation time are essentially different even though both arise from scattering by static impurities and defects.
“While both arise from the scattering by static impurities and defects, these two quantities are essentially different (217, 218):”
From Transport of Topological Semimetals (2019) · cites this paper as [217]
Section V (p. 5) defines a lifetime through the Dingle temperature and uses it to estimate surface mobility, but does not distinguish quantum from transport relaxation time. Section III (p. 3) discusses defects and carrier density, not whether both times arise from scattering by static impurities and defects. Searches for the two relaxation times and scattering did not locate the attributed comparison. (LLM, conf=0.72)

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.
