Superconducting Gap vs. Wave Vector: Evidence for Hot Regions on the Fermi Surface
R. Gatt, S. Christensen, B. Frazer +11
We have used angular resolved photoemission to measure the angular dependence of the superconducting gap in highly overdoped Bi2212 (Tc=65K). While the node at 45 degrees is conser…
Shadow bands in overdoped Bi_2Sr_2CaCu_2O_{8+x}
S. La Rosa, R. J. Kelley, C. Kendziora +3
We performed angle-resolved photoemission experiments on overdoped single crystal samples with Tc values as low as 55K and very narrow transitions as measur…
INTERLAYER COUPLING AND THE METAL-INSULATOR TRANSITION IN Pr-SUBSTITUTED Bi(2)Sr(2)CaCu(2)O(8+y)
C. Quitmann, B. Beschoten, R. J. Kelley +2
Substitution of rare-earth ions for Ca in Bi2Sr2CaCu2O8+y is known to cause a metal-insulator transition. Using resonant photoemission we study how this chemical substitution affec…
and Oxygen Stoichiometry: Structure, Resistivity, Fermi Surface Topology and Normal State Properties
Jian Ma, P. Alméras, R. J. Kelley +6
(2212) single crystal samples were studied using transmission electron microscopy (TEM), plane () and axis () res…
Localization Effects in Bi2Sr2Ca(Cu,Co)2O8+y High Temperature Superconductors
C. Quitmann, P. Almeras, Jian Ma +4
Doping Bi2Sr2Ca1Cu2O8+y with Co causes a superconductor-insulator transition. We study correlations between changes in the electrical resistivity RHOab(T) and the electronic bandst…
Localized electronic states and photoemission superconducting condensate in BiSrCaCuO
Jian Ma, C. Quitmann, R. J. Kelley +2
We present the first detailed angle-resolved photoemission evidence that there are two types of carriers that contribute to the photoemission superconducting condensate in $Bi_{2}S…
Observation of a van Hove Singularity in with Angle Resolved Photoemission
Jian Ma, C. Quitmann, R. J. Kelley +4
We have performed high energy resolution angle-resolved photoemission studies of the normal state band structure of oxygen overdoped . We find that…
Temperature dependence of the superconducting gap anisotropy in BiSrCaCuO
Jian Ma, C. Quitmann, R. J. Kelley +3
We present the first detailed data of the momentum-resolved, temperature dependence of the superconducting gap of , complemented by similar data on…
Effect of Iodine Doping on BiSrCaCuO: Charge Transfer or Interlayer Coupling?
Jian Ma, P. Alméras, R. J. Kelley +5
A comparative study has been made of iodine-intercalated BiSrCaCuO single crystal and 1 atm O annealed BiSrCaCuO s…
