The feedback driven atomic scale Josephson microscope
Samuel D. Escribano, Víctor Barrena, David Perconte +10
The ultimate spatial limit to establish a Josephson coupling between two superconducting electrodes is an atomic-scale junction. The Josephson effect in such ultrasmall junctions h…
Simplified feedback control system for Scanning Tunneling Microscopy
Francisco Martín-Vega, Víctor Barrena, Raquel Sánchez-Barquilla +18
A Scanning Tunneling Microscope (STM) is one of the most important scanning probe tools available to study and manipulate matter at the nanoscale. In a STM, a tip is scanned on top…
Superconductivity in a disordered metal with Coulomb interactions
Svetlana V. Postolova, Alexey Yu. Mironov, Víctor Barrena +6
We study the electronic densities of states (DOS) of strongly disordered superconducting thin films of TiN. We find, using Scanning Tunneling Microscopy (STM) that the DOS decrease…
Robust, switchable, C-related, Superconducting Nanostructure at the Apex of a W tip
C. G. AYani, F. Calleja, P. Casado +8
We report on a controlled method to fabricate in-situ a superconducting (SC) nanostructure at the apex of the standard W tip of a Scanning Tunnelling Microscope (STM) by pulsing th…
Imaging superconducting vortex core and lattice with the scanning tunneling microscope
H. Suderow, I. Guillamon, J. G. Rodrigo +1
The observation of vortices in superconductors was a major breakthrough in developing the conceptual background for superconducting applications. Each vortex carries a flux quantum…
Conductance behavior with temperature and magnetic field in the disordered films of titanium nitride
P. Kulkarni, H. Suderow, J. Rodrigo +4
We report in this paper the temperature and mangetic field dependence of the conductance in the polycrystalline film of titanium nitride, before and after heating at ambient condit…
