Niobium Nitride Thin Films and Multilayers for Srf Applications
نویسنده
چکیده
Superconducting thin films have the potential to overcome fundamental limitations of bulk niobium technology that is currently implemented in linear particle accelerators. Before these thin films can successfully be implemented, systematic studies on structureproperty correlations are necessary. Here, we present the characterization of niobium nitride thin films and multilayers. We explore the differences between niobium and niobium nitride surfaces. Additionally, we demonstrate that niobium nitride multilayers are capable of shielding an underlying niobium film from magnetic fields larger than the lower critical field of bulk niobium.

Preparation and Characterization of Aluminum Nitride Thin Films with the Potential Application in Electro-Acoustic Devices
In this work, aluminum nitride (AlN) thin films with different thicknesses were deposited on quartz and silicon substrates using single ion beam sputtering technique. The physical and chemical properties of prepared films were investigated by different characterization technique. X-ray diffraction (XRD) spectra revealed that all of the deposited films have an amorphous str...
متن کاملOptical Properties of Ultra - Thin Niobium Nitride Films for Single Photon Detectors by Lucy
In this thesis I made a study of the properties of reactively sputtered ultra-thin films of niobium nitride (NbN) and niobium titanium nitride (NbTiN). Using Variable Angle Spectral Ellipsometry (VASE), I found that the optical properties of NbN films appear to have a critical thickness above which the optical parameters stabilize. I also found that the deposition process has better stability o...

متن کاملMicrowave Surface Resistance of Reactively Sputtered NbN Thin Films
The surface resistance of niobium nitride {NbN) thin films has been measured at 7. 78 and 10.14 GHz in the temperature range of 1.5 to 4.2 K. The films were reactively sputtered on sapphire substrates to a thickness of approximately 1 micron. The surface resistance was determined by measuring the quality factor (Q) of the TEo] 1 mode of a lead-plated copper cavity where the NbN served as one en...
