Photoemission Evidence for a Remnant Fermi Surface and a d- Wave-Like Dispersion in Insulating Ca 2 CuO 2 Cl 2
Open accessAbstract
An angle-resolved photoemission study is reported on Ca 2 CuO 2 Cl 2 , a parent compound of high- T c superconductors. Analysis of the electron occupation probability, n( k ), from the spectra shows a steep drop in spectral intensity across a contour that is close to the Fermi surface predicted by the band calculation. This analysis reveals a Fermi surface remnant, even though Ca 2 CuO 2 Cl 2 is a Mott insulator. The lowest energy peak exhibits a dispersion with approximately the |cos k x a – cos k y a | form along this remnant Fermi surface. Together with the data from Dy-doped Bi 2 Sr 2 CaCu 2 O 8+δ , these results suggest that this d -wave–like dispersion of the insulator is the underlying reason for the pseudo gap in the underdoped regime.

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.
