Electronic structure of the trilayer cuprate superconductor BiSrCaCuO
D. L. Feng, A. Damascelli, K. M. Shen +14
The low-energy electronic structure of the trilayer cuprate superconductor BiSrCaCuO near optimal doping is investigated by angle-resolved photoemission sp…
Nature of the Electronic Excitations near the Brillouin Zone Boundary of BiSrCaCuO
D. L. Feng, C. Kim, H. Eisaki +12
Based on angle resolved photoemission spectra measured on different systems at different dopings, momenta and photon energies, we show that the anomalously large spectral linewidth…
Surface electronic structure of Sr2RuO4
K. M. Shen, A. Damascelli, D. H. Lu +12
We have addressed the possibility of surface ferromagnetism in Sr2RuO4 by investigating its surface electronic states by angle-resolved photoemission spectroscopy (ARPES). By cleav…
Momentum-Resolved Inelastic X-ray Scattering as a Novel Tool to Study Charge Gap in Complex Insulators
M. Z. Hasan, E. D. Isaacs, Z-X. Shen +1
We report particle-hole pair excitations in a cuprate insulator in the intermediate regimes of momentum-transfers using high energy inelastic x-ray scattering. The excitation spect…
Superconducting Gap and Strong In-Plane Anisotropy in Untwinned YBa2Cu3O7-d
D. H. Lu, D. L. Feng, N. P. Armitage +10
With significantly improved sample quality and instrumental resolution, we clearly identify in the (pi,0) ARPES spectra from YBa2Cu3O6.993, in the superconducting state, the long-s…
Bilayer Splitting in the Electronic Structure of Heavily Overdoped Bi2Sr2CaCu2O8+d
D. L. Feng, N. P. Armitage, D. H. Lu +11
The electronic structure of heavily overdoped BiSrCaCuO is investigated by angle-resolved photoemission spectroscopy. The long-sought bilayer band splitting in…
