Substrate-Induced Proximity Effect in Superconducting Niobium Nanofilms

Substrate-Induced Proximity Effect in Superconducting Niobium Nanofilms

Structural and superconducting properties of high-quality niobium nanofilms with different thicknesses are investigated on silicon oxide (SiO2) and sapphire substrates. The role played by the different substrates and the superconducting properties of the Nb films are discussed based on the defectivi...
