Dr. Laia Soler, former PhD researcher under the supervision of Prof. Xavier Obradors and Dr. Susagna Ricart defended her PhD thesis entitled Liquid-assisted ultrafast growth of superconducting films derived from chemical solutions publicly on 1 March 2019 at the ICMAB-CSIC Auditorium.
Date: Wednesday, 31 October 2018
Time: 11 am
Venue: Sala de Graus, Facultat de Ciències, UAB
Abstract: This thesis is mainly based on the understanding the synthesis and the final behaviour of the surface of LnF3 nanocrystals. In consequence, this knowledge will allow the control and manipulation of the bridge between synthesis and applications, currently called surface chemistry.
Starting from the successful synthesis of fifteen different types of inorganic nanocrystals, the general trends of metal fluoride nanocrystals is successfully unravelled. A new kind of ionic self-assembly in colloidal systems is postulated and thermodynamically stable patchy nanocrystals also obtained. Using experimental techniques and molecular dynamics simulations, a self assembly mechanism also applicable to other kind of systems is postulated and we demonstrate that the different facets of the patchy nanoparticles can be modified selectively.

Abstract: In this thesis, we investigate the structural distortions appearing in three different kind of perovskite oxides that are fabricated as thin films following a chemical solution deposition process. In the first case, we study how the YBCO lattice is distorted around its most common defect, this is the Y124 intergrowth. Secondly, we investigate which structural mechanisms help to accommodate the strain generated by the substrate mismatch in nickelate thin films. Finally, we study how the spatial confinement influences both the physical and structural properties of La0.7Sr0.3MnO3/SrTiO3 heterostructures.
