The discovery of superconductivity in doped infinite-layer nickelates has attracted great interest recently. Here, a metal-insulator-superconductor transition is demonstrated by engineering the process of topotactic reduction. By employing topotactic reduction, a superconducting Nd0.8Sr0.2NiO2 layer...
