Growth of Highly c-axis Oriented and/or Epitaxial Single-Domain b-axis Oriented La5Ca9Cu24O41 Thin Films by Pulsed Laser Deposition

Abstract

This project attempted to grow La5Ca9Cu24O41 (LCCO) films on important substrates with the high-thermal-conductivity direction parallel or perpendicular to the surface of the substrate, counting success as demonstration of b-axis or c-axis oriented LCCO films along with measurement of bulk thermal conductivity. We succeeded in b-axis, but all efforts concerning growth of c-axis oriented films were unsuccessful. We extensively studied the influence of pulsed laser deposition growth parameters, trying various substrates or trying substrates with a buffer layer, but were not able to investigate substrates covered with carbon nanotubes as nanostructures with the desired dimensions proved unobtainable.
