The normal state Fermi surface of pristine and Pb-doped Bi2212 from ARPES measurements and its photon energy independence
S. Legner, S. V. Borisenko, C. Duerr +10
We address the question as to whether the topology of the normal state Fermi surface of Bi2212 - as seen in angle resolved photoemission - depends on the photon energy used to meas…
Novel Fine-Structure in the Low-Energy Excitation Spectrum of a High-Tc Superconductor by Polarization Dependent Photoemission
R. Manzke, R. Mueller, C. Janowitz +3
Angle-resolved photoemission spectroscopy is performed on single crystals of the single-layer high-Tc superconductor Bi(2)Sr(2-x)La(x)CuO(6+d) at optimal doping (x=0.4) in order to…
Comparative study of the electronic structures of the In and Sn/In2O3 (111) interfaces
M. Nazarzahdemoafi, F. Titze, S. Machulik +4
The electronic structure of the transparent semiconductor In2O3 has been studied by angle resolved photoemission spectroscopy upon deposition of metallic indium and also tin on the…
Unusual electronic ground state of a prototype cuprate: band splitting of single CuO_2-plane Bi_2 Sr_(2-x) La_x CuO_(6+delta)
C. Janowitz, R. Mueller, L. Dudy +4
By in-situ change of polarization a small splitting of the Zhang-Rice singlet state band near the Fermi level has been resolved for optimum doped (x=0.4) BiSrLa…
Dependence of the gap parameter on the number of CuO2 layers in a unit cell of optimally doped BSCCO, TBCCO, HBCCO and HSCCO
Ya. G. Ponomarev, N. Z. Timergaleev, A. O. Zabezhaylov +8
We have measured the superconducting gap Ds in optimally doped samples of BSCCO, TBCCO, HBCCO and HSCCO by Andreev and tunnelling spectroscopy and by ARPES. We have found that the…
Structural behavior of PbBiSrLaCuO for 0<y<0.53
O. Lübben, L. Dudy, A. Krapf +2
In the Bi cuprates, the presence of a near 15 superstructure is well known. Usually, this superstructure is suppressed by the substitution of lead, but there have been repo…
