Temperature-Dependent Resistance Modulation in Niobium Films on Nickel Dot Arrays - Insights into Superconductivity

Explore temperature-dependent resistance modulation in niobium films deposited on square arrays of nickel dots in this 51-minute HyperComplex Seminar talk. Delve into the unique resistance behavior observed as temperature decreases, revealing an atypical pattern for superconducting films. Examine the intriguing phenomenon where resistance increases at a specific temperature (TRMAX) below the critical temperature Tc before dropping to zero. Investigate the formation of Josephson Junction-like areas within the niobium film, characterized by alternating strong and weak superconductivity regions, analogous to an array of S-N-S Josephson weak links. Gain insights into the behavior of niobium films in nanoscale magnetic environments and discover potential applications in quantum device engineering.
