  1. Planar Tunneling Spectroscopy of Thin-Film Niobium, Niobium/normal Metal and Niobium/semicondutor Structures

    Abeyta, Adam ChristopherUniversity of Illinois at Urbana-Champaign2015

    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 …

    Miceli, Paul Frank2011

    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 …
