Title: Distinct Superconducting Gap on Two Bilayer-Split Fermi Surface Sheets in Bi₂Sr₂CaCu₂O_8+δ Superconductor

Abstract

High resolution laser-based angle-resolved photoemission measurements are carried out on an overdoped superconductor Bi₂Sr₂CaCu₂O_8+δ with a T_c of 75 K. Two Fermi surface sheets caused by bilayer splitting are clearly identified with rather different doping levels: the bonding sheet corresponds to a doping level of 0.14, which is slightly underdoped while the antibonding sheet has a doping of 0.27 that is heavily overdoped, giving an overall doping level of 0.20 for the sample. Different superconducting gap sizes on the two Fermi surface sheets are revealed. The superconducting gap on the antibonding Fermi surface sheet follows a standard d-wave form while it deviates from the standard d-wave form for the bonding Fermi surface sheet. The maximum gap difference between the two Fermi surface sheets near the antinodal region is ~2 meV. Furthermore, these observations provide important information for studying the relationship between the Fermi surface topology and superconductivity, and the layer-dependent superconductivity in high temperature cuprate superconductors.

Disappearance of Superconductivity Due to Vanishing Coupling in the Overdoped Bi₂Sr₂CaCu₂O_8+δ

Journal Article Valla, Tonica ; Drozdov, I. K. ; Gu, G. D. - Nature Communications

In cuprate superconductors, superconductivity is accompanied by a ‘plethora of orders’, and phenomena that complicate our understanding of superconductivity in these materials. Prominent in the underdoped regime, these orders weaken or vanish with overdoping. Here, we approach the superconducting phase from the more conventional overdoped side. We present angle-resolve photoemission spectroscopy studies of Bi₂Sr₂CaCu₂O_8+δ, cleaved and annealed in ozone to increase the doping all the way to the non-superconducting phase. In this work, we show that the mass renormalizationin the antinodal region of the Fermi surface, associated with the structure in the quasiparticle self-energy, that possibly reflects the pairing, weakensmore »« less

Phase diagram of Bi₂Sr₂CaCu₂O_8+δ revisited

Journal Article Drozdov, Ilya K. ; Pletikosić, I. ; Kim, C. -K. ; ... - Nature Communications

In cuprate superconductors, the doping of carriers into the parent Mott insulator induces superconductivity and various other phases whose characteristic temperatures are typically plotted versus the doping level p. In most materials, p cannot be determined from the chemical composition, but it is derived from the superconducting transition temperature, T_c, using the assumption that the T_c dependence on doping is universal. Here, we present angle-resolved photoemission studies of Bi₂Sr₂CaCu₂O_8+δ, cleaved and annealed in vacuum or in ozone to reduce or increase the doping from the initial value corresponding to T_c = 91 K. We show that p can be determinedmore »« less

Temperature Evolution of Energy Gap and Band Structure in the Superconducting and Pseudogap States of Bi₂Sr₂CaCu₂O_8+δ Superconductor Revealed by Laser-Based Angle-Resolved Photoemission Spectroscopy

Journal Article Sun, Xuan ; Zhang, Wen-Tao ; Zhao, Lin ; ... - Chinese Physics Letters

For this study, we carry out detailed momentum-dependent and temperature-dependent measurements on Bi₂Sr₂CaCu₂O_8+δ (Bi2212) superconductor in the superconducting and pseudogap states by super-high resolution laser-based angle-resolved photoemission spectroscopy. The precise determination of the superconducting gap for the nearly optimally doped Bi2212 (T_c=91 K) at low temperature indicates that the momentum-dependence of the superconducting gap deviates from the standard d-wave form (cos(2Φ)). It can be alternatively fitted by including a high-order term (cos(6Φ)) in which the next nearest-neighbor interaction is considered. We find that the band structure near the antinodal region smoothly evolves across the pseudogap temperature without a signature ofmore »« less

Raman and ARPES combined study on the connection between the existence of the pseudogap and the topology of the Fermi surface in ${Bi}_{2} {Sr}_{2} {CaCu}_{2} O_{8 + δ}$

Journal Article Loret, B. ; Gallais, Y. ; Cazayous, M. ; ... - Physical Review B

Here, we study the behavior of the pseudogap in overdoped Bi₂Sr₂CaCu₂O_8+δ by electronic Raman scattering (ERS) and angle-resolved photoemission spectroscopy (ARPES) on the same single crystals. Using both techniques we find that, unlike the superconducting gap, the pseudogap related to the antibonding band vanishes above the critical doping p_c = 0.22 . Concomitantly, we show from ARPES measurements that the Fermi surface of the antibonding band is holelike below p_c and becomes electronlike above p_c. This reveals that the existence of the pseudogap depends on the Fermi surface topology in Bi₂Sr₂CaCu₂O_8+δ, and more generally, puts strong constraint on theories ofmore » the pseudogap phase.« less

Angle-Resolved Photoemission Spectroscopy on Electronic Structure and Electron-Phonon Coupling in Cuprate Superconductors

Journal Article Zhou, X J - Submitted to Book Chapter in Handbook of High-Temperature Superconductivity: Theory and Experiment (2007)

In addition to the record high superconducting transition temperature (T{sub c}), high temperature cuprate superconductors are characterized by their unusual superconducting properties below T{sub c}, and anomalous normal state properties above T{sub c}. In the superconducting state, although it has long been realized that superconductivity still involves Cooper pairs, as in the traditional BCS theory, the experimentally determined d-wave pairing is different from the usual s-wave pairing found in conventional superconductors. The identification of the pairing mechanism in cuprate superconductors remains an outstanding issue. The normal state properties, particularly in the underdoped region, have been found to be at oddmore »« less
