Doping Bi2Sr2Ca1Cu2O8+y with Co causes a superconductor-insulator transition. We study correlations between changes in the electrical resistivity rho(ab)(T) and the electronic bandstructure using identical single crystalline samples. For undoped samples th ...
A study of the formation of In- and Au-GaAs(100) interfaces is reported. The metal overlayers are deposited in ultrahigh vacuum on room-temperature (RT) and low-temperature (LT) (100)GaAs grown by molecular-beam epitaxy, following the evaporation of a prot ...
We used photoemission spectroscopy with synchrotron radiation to investigate the electronic structure of eight different thallium cuprates: pure Tl2.2Ba2CuO(y), Ce-doped Tl2.2Ba(2-x)Ce(x)CuO(y) (x = 0.1, 0.15, 0.2) and Tl2Ba2CeCu3O(y), and Zr-doped Tl2Ba(2 ...
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 ...
Using high energy resolution angle-resolved photoemission, we have measured both the superconducting gap and the photoemission superconducting condensate spectral area of Bi2Sr2Ca1Cu1O8+x as a function of temperature in two different locations of the Brill ...
The authors studied the electric structure of two high-temperature superconductors, with particular emphasis on photoemission resonance effects and on collective excitation phenomena. The photoemission resonances simplified the identification of valence sp ...
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 ...
Photoelectron spectroscopy with high-energy resolution has been utilized to investigate the charge-density wave (CDW) in 1T-TaS2 between 20 and 360 K. Constant binding-energy curves reveal discontinuities in the temperature dependence of the photoelectron ...
Using angle-resolved photoemission, we observed a nonzero superconducting gap and the presence of a superconducting condensate along all three major symmetry directions. We find that the gap is highly anisotropic, with a gap as small as 1-2 meV along GAMMA ...
Improved experimental conditions enabled us to increase the signal-to-noise ratio of the photoemission spectra for the superconducting state of Bi2Ca2SrCu2O8, taken with high angular and energy resolution. This also enabled us to reveal a pronounced minimu ...
