Synthesis and characterization of atomically-thin graphite films on a silicon carbide substrate
E. Rollings, G. -H. Gweon, S. Y. Zhou +7
This paper reports the synthesis and detailed characterization of graphite thin films produced by thermal decomposition of the (0001) face of a 6H-SiC wafer, demonstrating the succ…
Quasiparticle-like peaks, kinks, and electron-phonon coupling at the (,0) regions in the CMR oxide LaSrMnO
Z. Sun, Y. -D. Chuang, A. V. Fedorov +11
Using Angle-Resolved Photoemission (ARPES), we present the first observation of sharp quasiparticle-like peaks in a CMR manganite. We focus on the (,0) regions of k-space and st…
Laser ARPES, the sudden approximation, and quasiparticle-like peaks in Bi2Sr2CaCu2O8+delta
J. D. Koralek, J. F. Douglas, N. C. Plumb +9
A new low photon energy regime of angle resolved photoemission spectroscopy is accessed with lasers and used to study the superconductor Bi2Sr2CaCu2O8+delta. The low energy increas…
Nature of Correlated Motion of Electrons in the Parent Cobaltate Superconductors
M. Z. Hasan, D. Qian, Y. Li +5
Recently discovered class of cobaltate superconductors (Na0.3CoO2.nH2O) is a novel realization of interacting quantum electron systems in a triangular network with low-energy degre…
Fermi surface evolution and Luttinger theorem in NaCoO: a systematic photoemission study
H. -B. Yang, Z. -H. Pan, A. K. P. Sekharan +9
We report a systematic angle-resolved photoemission study on NaCoO for a wide range of Na concentrations (). In all the metallic samples at different…
