Liquid-assisted ultrafast growth of superconducting films derived from chemical solutions

by Laia Soler Bru, Superconducting Materials and Large Scale Nanostructures (SUMAN) Group, ICMAB

Date: Friday, 1 March 2019
Time: 11 am
Venue: Sala d'actes Carles Miravitlles, ICMAB-CSIC

Abstract: This thesis was devoted to the growth of textured YBa2Cu3O7-x superconducting thin films. We present a novel technique that relies on the kinetic preference to form a transient liquid that assists the ultrafast growth (100nm/s) of the equilibrium phase. Transient Liquid Assisted Growth (TLAG) is combined with low cost Chemical Solution Deposition (CSD) from carboxylate solutions.

This new approximation has been attained with the use of rapid thermal annealing (up to 80ºC/s). The reaction mechanisms are disclosed with in-situ analyses using infrared and X-ray diffraction. Finally, the supersaturation conditions for crystallization are tunned to nucleate the desired phase structure required to obtain good superconducting properties.
