Non-epitaxial perovskite polariton laser diode operating under direct current

Nature, Published online: 22 July 2026; doi:10.1038/s41586-026-10824-wBy integrating a solution-grown perovskite microplate with chemically inert single-walled carbon nanotube electrodes and embedding them into an optical microcavity, the new microdevices can achieve polariton lasing under a constant direct current at 8 K.
