Planar Tunneling Spectroscopy of Thin-Film Niobium, Niobium/normal Metal and Niobium/semicondutor Structures
The superconductor-semiconductor study was performed on Nb-InGaAs bilayers. The Schottky barrier formed at the interface between these two materials was utilized as a tunneling barrier. A method was developed to fabricate small area junctions. The tunneling conductance as a function of …

Hydrogen in niobium-tantalum superlattices
Hydrogen has been dissolved in Nb/Ta superlattices for which the structural and thermodynamic properties of this new H-metal system were studied, in situ, by x-ray diffraction. It is found that H induces a strain modulation exhibiting a Curie-Weiss type temperature dependence, thus, providing a …

Hydrogen in thin film niobium
… study of hydrogen dissolved in thin films of niobium is presented. The chief techniques used were x-ray diffraction and ion-beam hydrogen profiling. Niobium was grown on sapphire substrates by molecular beam epitaxy, resulting in high quality films. It has previously been shown that such films …
