High resolution angle resolved photoemission studies on quasi-particle dynamics in graphite
We obtained the spectral function of the graphite H point using high resolution angle resolved photoelectron spectroscopy (ARPES). The extracted width of the spectral function (inverse of the photo-hole lifetime) near the H point is approximately proportional to the energy as expected from the linearly increasing density of states (DOS) near the Fermi energy. This is well accounted by our elect...
متن کاملAngle-resolved photoemission study of Sr2RuO4.
We present high-resolution ~HR! angle-resolved photoemission spectroscopy ~ARPES! measurements of the noncuprate layered perovskite superconductor Sr2RuO4 . ARPES spectra of the whole valence-band region obtained along two high-symmetry directions in the Brillouin zone show clear dispersion, generally similar to that of a band calculation. However, HRARPES measurements taken in the vicinity of ...
متن کاملElectron-electron correlation in graphite: a combined angle-resolved photoemission and first-principles study.
The full three-dimensional dispersion of the pi bands, Fermi velocities, and effective masses are measured with angle-resolved photoemission spectroscopy and compared to first-principles calculations. The band structure by density-functional theory underestimates the slope of the bands and the trigonal warping effect. Including electron-electron correlation on the level of the GW approximation,...
متن کاملA tunable low-energy photon source for high-resolution angle-resolved photoemission spectroscopy.
We describe a tunable low-energy photon source consisting of a laser-driven xenon plasma lamp coupled to a Czerny-Turner monochromator. The combined tunability, brightness, and narrow spectral bandwidth make this light source useful in laboratory-based high-resolution photoemission spectroscopy experiments. The source supplies photons with energies up to ~7 eV, delivering under typical conditio...
متن کاملAngle-resolved photoemission in high Tc cuprates from theoretical viewpoints
The angle-resolved photoemission (ARPES) technique has been developed rapidly over the last decay, accompanied by the improvement of energy and momentum resolutions. This technique has been established as the most powerful tool to investigate the high Tc cuprate superconductors. We review recent ARPES data on the cuprates from a theoretical point of view, with emphasis on the systematic evoluti...
