Latest Patents
Francavilla holds a patent for a method of forming thin niobium carbonitride superconducting films. This patent describes a process where thin superconducting NbCN films are deposited by reactive sputtering onto a dielectric substrate inside a vacuum chamber. The substrate is heated to a temperature between 600 and 1200 degrees Celsius. Ultra-pure Argon is introduced into the chamber, and niobium is presputtered from a high-purity target onto a shutter. A cyanogen and nitrogen gas mixture is introduced into the chamber at a rate of approximately 10^-6 Torr liters/sec. The shutter is then opened, exposing the substrate to the sputtered niobium. The deposited niobium reacts with the cyanogen-nitrogen gas mixture to form NbCN films of exceptional purity, which exhibit superior superconductor properties.
