Author:Elkaseh, A; Buttner, U; Srinivasu, VV; Perold, WJDate:Apr 2009AFM nanolithography was used as a novel cutting technique to define micro-size YBCO superconducting constrictions. Researchers studied the substrate effects on MgO and STO substrates and showed that the observed Shapiro steps from the bridges ...Read more
Author:Elkaseh, AAO; Srinivasu, VV; Perold, WJDate:2009Using an Atomic Force Microscope (AFM), micron size planar constriction type junctions was successfully ploughed on YBa2Cu3O7-x thin films. The 100 nanometer (nm) thin films are deposited on MgO substrates by an Inverted Cylindrical Magnetron ...Read more
Author:Van Staden, WF; Buttner, U; Fourie, CJ; Srinivasu, VV; Hardie, GL; Perold, WJDate:Apr 2009Bilayers of PBCO and YBCO are grown epitaxially on MgO substrates using PLD. In this paper, researchers discuss the entire optimization process in detail, giving quantitative parameter values. Film characterization included XRD, AFM and ...Read more
