Superconducting Gap Anisotropy in NdCeCuO: Results from Photoemission
N. P. Armitage, D. H. Lu, D. L. Feng +8
We have performed angle resolved photoelectron spectroscopy on the electron doped cuprate superconductor NdCeCuO. A comparison of the leading edge midpoints b…
Angle-resolved photoemission study of insulating and metallic Cu-O chains in PrBaCuO and PrBaCuO
T. Mizokawa, C. Kim, Z. -X. Shen +17
We compare the angle-resolved photoemission spectra of the hole-doped Cu-O chains in PrBaCuO (Pr123) and in PrBaCuO (Pr124). While, in Pr123, a dispersive f…
Electron-Like Fermi Surface and Remnant (pi,0) Feature in Overdoped La1.78Sr0.22CuO4
T. Yoshida, X. J. Zhou, M. Nakamura +13
We have performed an angle-resolved photoemission study of overdoped La1.78Sr0.22CuO4, and have observed sharp nodal quasiparticle peaks in the second Brillouin zone that are compa…
Dual Nature of the Electronic Structure of the Stripe Phase
X. J. Zhou, T. Yoshida, S. A. Kellar +11
High resolution angle-resolved photoemission measurements have been carried out on (La_1.4-xNd_0.6Sr_x)CuO_4, a model system with static stripes, and (La_1.85Sr_0.15)CuO_4, a high…
Angle resolved photoemission spectroscopy of Sr_2CuO_2Cl_2 - a revisit
C. Duerr, S. Legner, R. Hayn +16
We have investigated the lowest binding-energy electronic structure of the model cuprate Sr_2CuO_2Cl_2 using angle resolved photoemission spectroscopy (ARPES). Our data from about…
Fermi Surface, Surface States, and Surface Reconstruction in Sr2RuO4
A. Damascelli, D. H. Lu, K. M. Shen +9
The electronic structure of Sr2RuO4 is investigated by high angular resolution ARPES at several incident photon energies. We address the controversial issues of the Fermi surface (…
ARPES study of Pb doped Bi_2Sr_2CaCu_2O_8 - a new Fermi surface picture
P. V. Bogdanov, A. Lanzara, X. J. Zhou +7
High resolution angle resolved photoemission data from Pb doped Bi_2Sr_2CaCu_2O_8 (Bi2212) with suppressed superstructure is presented. Improved resolution and very high momentum s…
Evidence for an energy scale for quasiparticle dispersion in Bi_2Sr_2CaCu_2O_8
P. V. Bogdanov, A. Lanzara, S. A. Kellar +8
Quasiparticle dispersion in is investigated with improved angular resolution as a function of temperature and doping. Unlike the linear dispersion predi…
