Angle-resolved photoemission data taken on some Bi2Sr2CaCu2O8+y single crystals exhibit the formation of a superconducting gap in the absence of a quasiparticle normal state band. We observe the opening of the superconducting gap in the same regions of the ...
We have studied the influence of Co and Ni doping on the electronic band structure and the transport properties of high-temperature superconductors. The doping has dramatic effects on both the normal and the superconducting state. Upon doping the residual ...
Cobalt-doping of Bi2Sr2CaCu2Ox beyond a critical level of 1.5-1.7 at % produces both a large decrease in the superconducting transition critical temperature and all of the classic symptoms of Anderson localization. These include: a negative slope of the ab ...
We calculate the one-particle spectral functions above the superconducting transition temperature TC, in the framework of a functional integral approach. The coupling of the electronic self-energy to pair fluctuations, which are treated by means of a time- ...
We present an update on recent events concerning ultrabright synchrotron radiation. First and foremost, a new generation of sources has been put in operation in the past few months. Second, microscopy and spectromicroscopy - arguably the techniques that wi ...
We measured at high energy and angular resolution the spectral width of photoemission features near the Fermi energy for Ag(100) and for the nearly-two-dimensional metal 2H-NbSe2. The results do not agree with the quadratic width-energy relationship predic ...
Thirteen years ago, late in 1986, several groups confirmed striking claims of the famous paper by Bednorz and Muller [see Z Phys. B, vol.64, p.189 (1986)] that announced the discovery of high-Tc superconductivity in cuprates. Some 60000 papers later, we ar ...
We have exploited angle-resolved photoelectron spectroscopy to study changes in the quasiparticle excitations of CuO2 planes as a function of the carrier density, in optimally doped and underdoped Bi2Sr2CaCuO8+x and in Sr2CuO2Cl2. We have observed large ch ...
We used thermal neutron irradiation to produce disorder in Bi-2212 single crystals (T-c = 85 K), at a constant carrier density. The irradiated samples were insulators. High-temperature superconductivity with a lower T-c than prior to irradiation could be r ...
Using angle-resolved photoemission and linearly polarized synchrotron radiation, we measured the electronic band structure of electronic states of CuO2 plane materials ranging from insulators (Sr2CuO2Cl2) to overdoped superconductors (Bi2Sr2CaCu2O8+x). We ...
