Fast Track to the Overdoped Regime of Superconducting YBa2Cu3O7‐δ Thin Films via Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.
