Electric pulse induced electronic patchwork in the Mott insulator GaTaSe
Vincent Dubost, Tristan Cren, François Debontridder +6
Following a recent discovery of the Insulator-to-Metal Transition induced by electric field in GaTaSe, we performed a detailed Scanning Tunneling Microscopy/Spectroscop…
Disorder effects in pnictides : a tunneling spectroscopy study
Y. Noat, T. Cren, V. Dubost +6
We present the synthesis and the tunneling spectroscopy study of superconducting FeSe0.5Te0.5 (Tc = 14 K), SmFeAsO0.85 (Tc = 45 K) and SmFeAsO0.9F0.1 (Tc = 52 K). The samples were…
Evidence for Scattering-Dependent Multigap Superconductivity in Ba8Si46
Yves Noat, Tristan Cren, Pierre Toulemonde +4
We have studied the quasiparticle excitation spectrum of the superconductor Ba8Si46 by local tunneling spectroscopy. Using high energy resolution achieved in Superconductor-Superco…
Electric Pulse Induced Resistive Switching, Electronic Phase Separation, and Possible Superconductivity in a Mott insulator
C. Vaju, L. Cario, B. Corraze +6
Metal-insulator transitions (MIT) belong to a class of fascinating physical phenomena, which includes superconductivity, and colossal magnetoresistance (CMR), that are associated w…
Scanning Tunneling Spectroscopy on the novel superconductor CaC6
N. Bergeal, V. Dubost, Y. Noat +7
We present scanning tunneling microscopy and spectroscopy of the newly discovered superconductor CaC. The tunneling conductance spectra, measured between 3 K and 15 K, show a c…
