Superconducting nanoribbon with a constriction: A quantum-confined Josephson junction
L. Flammia, L. -F. Zhang, L. Covaci +2
Extended defects are known to strongly affect nanoscale superconductors. Here we report the properties of superconducting nanoribbons with a constriction formed between two adjacen…
Multifaceted impact of a surface step on superconductivity in atomically thin films
L. -F. Zhang, L. Flammia, L. Covaci +2
Recent experiments show that an atomic step on the surface of atomically thin metallic films can strongly affect electronic transport. Here we reveal multiple and versatile effects…
The Tomasch effect in nanoscale superconductors
L. -F. Zhang, L. Covaci, F. M. Peeters
The Tomasch effect (TE) is due to quasiparticle interference (QPI) as induced by a nonuniform superconducting order parameter, which results in oscillations in the density of state…
Position-dependent effect of non-magnetic impurities on superconducting properties of nanowires
L. -F. Zhang, L. Covaci, F. M. Peeters
Anderson's theorem states that non-magnetic impurities do not change the bulk properties of conventional superconductors. However, as the dimensionality is reduced, the effect of i…
Vortex states in nanoscale superconducting squares: the influence of quantum confinement
L. -F. Zhang, L. Covaci, M. V. Milošević +2
Bogoliubov-de Gennes theory is used to investigate the effect of the size of a superconducting square on the vortex states in the quantum confinement regime. When the superconducti…
