Evolution of the Fermi Surface with Carrier Concentration inBi2Sr2CaCu2O8+δ
Open accessAbstract
We show, by use of angle-resolved photoemission spectroscopy, that underdoped ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}$ appears to have a large Fermi surface centered at $(\ensuremath{\pi},\ensuremath{\pi})$, even for samples with a ${T}_{c}$ as low as 15 K. No clear evidence of a Fermi surface pocket around $(\ensuremath{\pi}/2,\ensuremath{\pi}/2)$ has been found. These conclusions are based on a determination of the minimum gap locus in the pseudogap regime ${T}_{c}<T<{T}^{*}$, which is found to coincide with the locus of gapless excitations in momentum space (Fermi surface) determined above ${T}^{*}$. These results suggest that the pseudogap is more likely of precursor pairing rather than magnetic origin.

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.
