Abstract

The microwave surface resistance of superconducting YBa2Cu3O7-δ thin films deposited by pulsed organometallic beam epitaxy (POMBE) has been characterized using the parallel plate transmission line resonator method. POMBE is an advanced organometric chemical vapor deposition technique where precursor vapors are precisely metered onto the substrate under computer control. In this study, the POMBE reactor was used to deposit epitaxial films of varying thickness onto LaAlO3 substrates. The deposition procedure and surface-resistance results for films of varying thicknesses are described. The reduction of surface resistance achieved supports the use of the POMBE technique as a possible method for preparing device-quality high-Tc films and multi-layer structures.
