Fermi surface, pseudogaps and dynamical stripes in La2-xSrxCuO4
A. Fujimori, A. Ino, T. Yoshida +6
Doping dependence of the electronic structure of LaSrCuO (LSCO) has been systematically studied in a series of photoemission measurements. The unusual spectral feat…
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…
The dynamics of a hole in a CuO_4 plaquette: electron energy-loss spectroscopy of Li_2CuO_2
S. Atzkern, M. Knupfer, M. S. Golden +7
We have measured the energy and momentum dependent loss function of Li_2CuO_2 single crystals by means of electron energy-loss spectroscopy in transmission. Using the same values f…
Doping dependent evolution of the electronic structure of La2-xSrxCuO4 in the superconducting and metallic phases
A. Ino, C. Kim, M. Nakamura +7
The electronic structure of the LaSrCuO (LSCO) system has been studied by angle-resolved photoemission spectroscopy (ARPES). We report on the evolution of the Fermi…
