Temperature-Dependent Dielectric Function of Tantalum Nitride Formed by Atomic Layer Deposition for Tunnel Barriers in Josephson Junctions
Ekta Bhatia, Aaron Lopez Gonzalez, Yoshitha Hettige +9
We report the dielectric functions of insulating tantalum nitride (TaN) films, deposited using atomic layer deposition (ALD) on 300 mm Si/SiO2 substrates, to demonstrate their suit…

Cryogenic growth of aluminum: structural morphology, optical properties, superconductivity and microwave dielectric loss
Wilson J. Yánez-Parreño, Teun A. J. van Schijndel, Anthony P. McFadden +7
We explore the molecular beam epitaxy synthesis of superconducting aluminum thin films grown on c-plane sapphire substrates at cryogenic temperatures of 6 K and compare their behav…
