Influence of the atomic-scale inhomogeneity of the pair interaction on extracted from the STM spectra characteristics of high- superconductors
A. M. Bobkov, I. V. Bobkova
The influence of the atomic-scale inhomogeneities of the pairing interaction strength on the superconducting order parameter and the conductance spectra measurable by STM is studie…
Local tunneling spectroscopy of the electron-doped cuprate Sm1.85Ce0.15CuO4
A. Zimmers, Y. Noat, T. Cren +4
We present local tunneling spectroscopy in the optimally electron-doped cuprate Sm2-xCexCuO4 x=0.15. A clear signature of the superconducting gap is observed with an amplitude rang…
Quasiparticle spectrum of the cuprate BiSrCaCuO: Possible connection to the phase diagram
W. Sacks, T. Cren, D. Roditchev +1
We previously introduced [T. Cren et al., Europhys. Lett. 52, 203 (2000)] an energy-dependant gap function, , that fits the unusual shape of the quasiparticle (QP) spectrum f…
Probing the superconducting condensate on a nanometer scale
Th. Proslier, A. Kohen, Y. Noat +3
Superconductivity is a rare example of a quantum system in which the wavefunction has a macroscopic quantum effect, due to the unique condensate of electron pairs. The amplitude of…
Probing the superfluid velocity with a superconducting tip: the Doppler shift effect
A. Kohen, Th. Proslier, T. Cren +4
We address the question of probing the supercurrents in superconducting (SC) samples on a local scale by performing Scanning Tunneling Spectroscopy (STS) experiments with a SC tip.…
Superconducting vortex profile from fixed point measurements The Lazy Fisherman tunnelling microscopy method
A. Kohen, T. Cren, Th. Proslier +7
We introduce a mode of operation for studying the vortex phase in superconductors using scanning tunnelling microscopy (STM). While in the conventional STM method, the tip is scann…
