Superconductor-insulator transitions in infinite-layer nickelates controlled via operando monitored reduction

Key Points

• Superconductor-insulator transition is observed as a function of reduction, suggesting a novel approach to manipulating material states.
• Operando monitored reduction impacts the electronic properties significantly, with observations of distinct phase changes in the nickelates.
• Assessment of infinite-layer nickelates under dynamic conditions shows a clear transition, revealing insights into electronic behavior.
• This work highlights the potential for innovative material design strategies based on reduction techniques.
