The electronic structures of the quenched superconductivity system Y 1-x Pr x Ba 2 Cu 3 O 7-δ (YPrBCO; x = 0, 0.4, 0.8) have been investigated by angle-resolved photoemission spectroscopy (ARPES). With increasing x, the ARPES spectra along Γ → S

The potassium doped monophosphate tungsten bronzes KxP4W8O32 are two-dimensional metals which show a metal-to-metal transition at a critical temperature which depends on the doping level. The metal-to-metal transition is accompanied by the formation

In recent years insight has been gained into the electronic structure of layered cuprates using angle-resolved photoelectron spectroscopy. In many of these studies it is assumed that the electron-photon matrix element follows the trends set by the at

Objective: We have recently shown that spontaneous Ca2+ oscillations elicit irreversible hypercontracture of cardiomyocytes during reoxygenation. The aim of this study was to investigate whether influx of exterior Ca2+ through the reverse mode of the

Little is known about the impact of the electron-photon matrix element on angle-resolved photoelectron spectra of layered cuprate compounds. Using the example of the model layered cuprate Sr{sub 2}CuO{sub 2}Cl{sub 2}, we demonstrate that the electron

The first electron-removal states of the layered cuprate Ba2Cu3O4Cl2 were measured using angle-resolved photoelectron spectroscopy. The symmetry and energy-momentum relations of the lowest-lying states were determined and interpreted in terms of the

Satellites on the low-binding-energy side of core-level photoelectron emission due to extra 4f screening are a well-known feature in the x-ray photoelectron spectra of valence fluctuation materials and rare-earth metals. A notable exception is Eu met

We report studies of the electronic structure and elementary excitations of undoped, one- and two-dimensional cuprates. Using high-energy spectroscopies such as X-ray absorption, photoemission and electron energy-loss spectroscopy, important informat
