Tin perovskite transistors stabilized through volatile coordination

Nature, Published online: 01 July 2026; doi:10.1038/s41586-026-10714-1 A volatile-assisted coordination strategy regulates surface defect chemistry and self-doping, thus stabilizing the stoichiometry of tin perovskite semiconductors, resulting in transistors that can maintain stable operation for a month at temperatures of 100 °C.
