Nanocrystalline metals have been an area of great interest in recent years due to their enhanced characteristics. One of the most striking is implied by the Hall-Petch relation: with decreasing grain size the material becomes stronger. This promise is fulf ...
A review is given of recent angle-resolved photoemission (ARPES) experiments and analyses on a series of layered charge density wave materials. Important aspects of ARPES are recalled in view of its capability for bulk band, Fermi surface and spectral func ...
Using high-resolution angle-resolved photoemission spectroscopy we have studied the momentum and photon energy dependence of the anomalous high-energy dispersion, termed waterfalls, between the Fermi level and 1 eV binding energy in several high-T-c superc ...
The electronic band structure probed by angle-resolved photoemission spectroscopy on thin epitaxial La_(2−x)Sr_(x)CuO_(4) films under extreme tensile strain shows anomalous features compatible with c-axis dispersion. This result is in striking contrast wit ...
A remarkable feature of layered transition-metal oxides-most famously, the high-temperature superconductors-is that they can display hugely anisotropic electrical and optical properties (for example, seeming to be insulating perpendicular to the layers and ...
We present ultraviolet photoelectron spectroscopy studies on alkali metal-intercalated thin films of electroluminescent p-sexiphenyl (6P) and the organic hole transporting material N,N'-bis-(1-naphthyl)-N,N'-diphenyll-1,1-biphenyl1-4,4'-diamine (alpha-NPD) ...
We have combined large-scale, Gamma-point electronic-structure calculations with the maximally localized Wannier functions approach to calculate efficiently the band structure and the quantum conductance of complex systems containing thousands of atoms whi ...
We present recent results obtained with a novel spectrometer developed within the EU project VOLPE (VOLume PhotoEmission from solids with synchrotron radiation), now operational at ESRF (Beamline ID 16), where we were able to achieve high energy resolution ...
Application of coating fragmentation test for determination of coating properties is considered. A probabilistic model of coating fragmentation under uniaxial tensile loading is applied for coating and interface property identification of thin brittle coat ...
We have optimized laser ablation thin film deposition and transfer procedures within synchrotron vault, specifically to perform angle-integrated and angle-resolved photoemission spectroscopy (ARPES) on high-T-c and related films without cleaving the sample ...
