Niobium-Tantalum Superlattices Grown by Molecular Beam Epitaxy: Structure, Transport, and Superconducting Properties
Abstract
dc:descriptionSingle crystal Nb-Ta superlattices with wavelengths from 20 to 800 (ANGSTROM) were fabricated in this work by Molecular Beam Epitaxy (MBE) techniques. For the first time, electronic mean free paths and crystal domain sizes were much larger than the imposed wavelength in metallic superlattices. X-ray structure factor determinations of superlattices grown in four different crystal orientations found that interfacial alloying was strongly direction dependent. The extent of intermixing was larger than predicted by simple diffusion, indicating mixing due to the kinetics of the deposition process.
