First direct observation of the Van Hove singularity in the tunneling spectra of cuprates
A. Piriou, N. Jenkins, C. Berthod +2
In two-dimensional lattices the electronic levels are unevenly spaced, and the density of states (DOS) displays a logarithmic divergence known as the Van Hove singularity (VHS). Th…
Phonon Mode Spectroscopy, Electron-Phonon Coupling and the Metal-Insulator Transition in Quasi-One-Dimensional M2Mo6Se6
A. P. Petrović, R. Lortz, G. Santi +9
We present electronic structure calculations, electrical resistivity data and the first specific heat measurements in the normal and superconducting states of quasi-one-dimensional…
Multi-band Superconductivity in the Chevrel Phases SnMo6S8 and PbMo6S8
A. P. Petrović, R. Lortz, G. Santi +10
Sub-Kelvin scanning tunnelling spectroscopy in the Chevrel Phases SnMo6S8 and PbMo6S8 reveals two distinct superconducting gaps with Delta_1 = 3 meV, Delta_2 ~ 1.0 meV and Delta_1…
Modeling scanning tunneling spectra of
B. W. Hoogenboom, C. Berthod, M. Peter +2
Recent angle-resolved photoemission and neutron scattering data have provided new ingredients for the interpretation of scanning tunneling spectra on BiSrCaCuO.…
Vortex Imaging in the pi-Band of Magnesium Diboride
M. R. Eskildsen, M. Kugler, S. Tanaka +4
We report scanning tunneling spectroscopy imaging of the vortex lattice in single crystalline MgB2. By tunneling parallel to the c-axis, a single superconducting gap (Delta = 2.2 m…
Shape and Motion of Vortex Cores in Bi_2Sr_2CaCu_2O_{8+δ}
B. W. Hoogenboom, M. Kugler, B. Revaz +3
We present a detailed study on the behaviour of vortex cores in Bi_2Sr_2CaCu_2O_{8+δ} using scanning tunneling spectroscopy. The very irregular distribution and shape of the vortex…
