Observation of shapiro-steps in AFM-plough micron-size YBCO planar constrictions

Srinivasu V.V.; Perold W.J.; Srinivasu V.V.; Perold W.J. (2009)

Using an Atomic Force Microscope (AFM), we successfully ploughed micron size planar constriction type junctions on YBa3Cu30 7-x thin films. The 100 nanometer (nm) thin films are deposited on MgO substrates by an Inverted ...
The enhancement of superconducting YBa2Cu30 7-x thin films by electric field application during deposition

Hardie G.L.; Buttner U.; Perold W.J. (2009)

The effect of applying a high electric field in-situ during the deposition and growth of YBa2Cu307-x (YBCO) thin films is investigated. The YBCO films are deposited from a stoichiometric YBCO target by pulsed laser deposition ...
