Journal ArticleDOI
Excitation Gap in the Normal State of Underdoped Bi2Sr2CaCu2O8+δ
A. G. Loeser,Zhi-Xun Shen,Daniel Dessau,Daniel S. Marshall,C. H. Park,Patrick Fournier,Aharon Kapitulnik +6 more
TL;DR: Angle-resolved photoemission experiments reveal evidence of an energy gap in the normal state excitation spectrum of the cuprate superconductor Bi2Sr2CaCu2O8+δ and the momentum dependence and magnitude closely resemble those of the dx2−y2 gap observed in the superconducting state.
Journal ArticleDOI
Anomalously large gap anisotropy in the a - b plane of Bi 2 Sr 2 CaCu 2 O 8 + δ
Zhi-Xun Shen,Zhi-Xun Shen,Daniel Dessau,Daniel Dessau,Barrett Wells,Barrett Wells,D. M. King,D. M. King,W. E. Spicer,W. E. Spicer,A. J. Arko,A. J. Arko,Daniel S. Marshall,Daniel S. Marshall,L. W. Lombardo,L. W. Lombardo,Aharon Kapitulnik,Aharon Kapitulnik,P. H. Dickinson,P. H. Dickinson,Sebastian Doniach,Sebastian Doniach,J. DiCarlo,J. DiCarlo,T. Loeser,T. Loeser,C. H. Park,C. H. Park +27 more
TL;DR: In this paper, the gap size reaches a maximum of approximately 20 meV along the Cu-O bond direction, and a minimum of much smaller or vanishing magnitude 45\ifmmode^\circ\else\text degree\fi{} away.
Journal ArticleDOI
Unconventional electronic structure evolution with hole doping in Bi2Sr2CaCu2O8+ delta : Angle-resolved photoemission results.
Daniel S. Marshall,Daniel Dessau,Daniel Dessau,A. G. Loeser,C. H. Park,A. Y. Matsuura,James N. Eckstein,Ivan Bozovic,Patrick Fournier,Aharon Kapitulnik,W. E. Spicer,Zhi-Xun Shen +11 more
TL;DR: Near optimal hole doping, the Fermi surface is large and consistent with band calculations, and in underdoped samples with ${T}_{c} of 60\char21{}70 K, portions of this Fermani surface are not seen.
Journal ArticleDOI
Key features in the measured band structure of Bi2Sr2CaCu2O8+ delta : Flat bands at EF and Fermi surface nesting.
Daniel Dessau,Z.-X. Shen,D. M. King,Daniel S. Marshall,L. W. Lombardo,P. H. Dickinson,A. G. Loeser,J. DiCarlo,C. H. Park,Aharon Kapitulnik,W. E. Spicer +10 more
TL;DR: Comparative analysis of these data with those from other cuprate superconductors suggests that features of the measured band structure may be responsible for many of the anomalous physical properties of the p-type cuprates, while the absence of these features may be related to the more ``normal'' physical Properties of the n types.
