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…
