Key Points

Simulations highlighted differences in island density predictions, emphasizing the need for better optimization methods.
Experimental validation demonstrated limitations of current models, suggesting potential improvements through data assimilation methods.
Using a monte carlo simulation and bayesian optimization approach may yield optimal growth parameters for REBCO thin films.
The findings set a basis for enhanced modeling methods that could significantly improve applications of high-temperature superconductors.

Implication

Analysis reveals discrepancies between monte carlo simulations and experimental crystal growth in REBCO thin films, indicating room for improved modeling.

Abstract

YBCO superconductors offer high transition temperatures for applications. REBCO wires, made via pulsed laser deposition (PLD), are developed for various uses. However, optimizing PLD parameters is time-consuming. To resolve this, we aimed to develop the simulation of REBCO thin film growth with Monte Carlo algorithm and Bayesian optimization to find the optimal parameters. While current simulations show discrepancies with experiments, this approach sets the foundation for improved models and simulations.
