Description
This work investigates the fabrication of NbN thin films superconductor by nitrogen-ion implantation into a 600 nm niobium thin film. SRIM and TRIDYN simulations are used to investigate ion distribution, sputtering, and compositional evolution at different implantation fluences. The structural characteristics are examined using X-ray diffraction (XRD), while electrical resistance measurements as a function of temperature and magnetic field are performed to characterize superconductivity. The high-fluence sample(S5-4e17) exhibits a superconducting transition temperature of approximately 10.2 K. Upper critical field curves are analyzed using the Ginzburg–Landau model. This study explores ion implantation as an alternative fabrication route and investigates the relationship between implantation fluence, structural characteristics, and superconducting properties.
