PlumX: High Performance of Superconducting YBa2Cu3O7 Thick Films Prepared by Single-Deposition Inkjet Printing

Inkjet printing (IJP) is a very appealing cost-effective deposition technique to achieve large-area solution-derived functional films. For many applications, it is very challenging to increase the film thickness in order to achieve competitive performance, for instance, high critical currents in superconducting films. In this paper, the preparation of superconducting YBa₂Cu₃O₇ thick films (∼1.1 μm) using a single deposition is reported. Specific rules for ink design, deposition protocols, and pyrolysis processes are provided.

PlumX: Ultra-high critical current densities of superconducting YBa2Cu3O7-δ thin films in the overdoped state

The functional properties of cuprates are strongly determined by the doping state and carrier density. We present an oxygen doping study of YBa₂Cu₃O_7-δ (YBCO) thin films from underdoped to overdoped state, correlating the measured charge carrier density, nHnH, the hole doping, p, and the critical current density, J_c. Our results show experimental demonstration of strong increase of J_c with n_H, up to Quantum Critical Point (QCP), due to an increase of the superconducting condensation energy.

PlumX: Combinatorial Screening of Cuprate Superconductors by Drop-On-Demand Inkjet Printing

Combinatorial and high-throughput experimentation (HTE) is achieving more relevance in material design, representing a turning point in the process of accelerated discovery, development, and optimization of materials based on data-driven approaches. The versatility of drop-on-demand inkjet printing (IJP) allows performing combinatorial studies through fabrication of compositionally graded materials with high spatial precision, here by mixing superconducting REBCO precursor solutions with different rare earth (RE) elements.

Pyrolysis study of solution-derived superconducting YBa2Cu3O7 films: disentangling the physico-chemical transformations

Written on 02 October 2020.

Chemical solution deposition (CSD) of epitaxial YBa₂Cu₃O₇ (YBCO) films is a high throughput, cost-effective approach to grow high critical current superconducting conductors for power applications. Achieving high critical currents requires to grow epitaxial films with large thicknesses and this is still an open issue in CSD.
