Synthesis and Characterization of Superconducting Electronic Materials.

Abstract

Specialized vacuum deposition systems were developed with the necessary monitoring and control to synthesize or react refractory superconducting films. NbN, VN, NbTi, and VTi films of high quality have been produced and their transport and tunneling properties studied. Ultra-thin films of pure Nb have been successfully made to study spin-orbit scattering in transition metals. The structural properties and penetration depth of NbN films prepared by reactive sputtering have been studied. Many-body effects which are important in superconductivity have been observed by spin-polarized tunneling and the antisymmetric Fermi liquid parameter has been measured for the first time in Al. The technique of deconvoluting tunneling conductance curves to obtain the superconducting density of states has been improved. A comprehensive study was made of amorphous Ge tunnel barriers between superconductors. (Author).
