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…
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…
