Fermi surface and electronic structure of Pb/Ge„111..
The electronic structure of Pb/Ge~111! has been probed along the temperature-induced phase transition a 2A33A3R30°⇒333 using angle-resolved photoemission. The a2A33A3R30° phase is metallic due to the existence of a half-filled, dispersing surface band. The 333 phase is characterized by the appearance of an additional surface band with 333 periodicity, whose role in the phase transition is discu...
متن کاملFermi surface topology of LaFePO and LiFeP.
We perform charge self-consistent density functional theory combined with dynamical mean field theory calculations to study correlation effects on the Fermi surfaces of the iron pnictide superconductors LaFePO and LiFeP. We find a distinctive change in the topology of the Fermi surface in both compounds where a hole pocket with Fe d(z(2)) orbital character changes its geometry from a closed sha...
متن کاملPb0.4Bi1.6Sr2CaCu2O8+x and oxygen stoichiometry: Structure, resistivity, Fermi-surface topology, and normal-state properties.
Pb0.4Bi1.6Sr2CaCu2O8+x (Bi(Pb)−2212) single crystal samples were studied using transmission electron microscopy (TEM), ab−plane (ρab) and c−axis (ρc) resistivity, and high resolution angle-resolved ultraviolet photoemission spectroscopy (ARUPS). TEM reveals that the modulation in the b−axis for Pb(0.4)−doped Bi(Pb)−2212 is dominantly of Pb−type that is not sensitive to the oxygen content of the...
متن کاملElectron correlation and fermi surface topology of NaxCoO2.
The electronic structure of NaxCoO2 revealed by recent photoemission experiments shows important deviations from band theory predictions. The six small Fermi surface pockets predicted by local-density approximation calculations have not been observed as the associated e'(g) band fails to cross the Fermi level for a wide range of sodium doping concentration x. In addition, significant bandwidth ...
متن کاملElectronic structure and the Fermi surface of ThRhIn5 in comparison with uranium and transuranium compounds
By using a relativistic linear augmented-plane-wave method, we clarify energy band structure and the Fermi surfaces of recently synthesized thorium compound ThRhIn5. We find several cylindrical Fermi surface sheets, which are similar to those of CeTIn5 (T=Ir and Co), PuTGa5 (T=Co and Rh), and AmCoGa5. We discuss such similarity among the compounds including rare-earth or actinide ions with diff...
