Perovskite Polariton Laser Diode Achieves Direct Current Operation

AI-synthesized · Bias removed · Facts only

Researchers have developed a new perovskite polariton laser diode that operates under direct current at extremely low temperatures. The device integrates solution-grown perovskite with carbon nanotube electrodes and an optical microcavity, representing a step forward in the field of optoelectronics.

The research, published online on July 22, 2026, details the creation of microdevices capable of achieving polariton lasing under a constant direct current. This was accomplished by integrating a solution-grown perovskite microplate with chemically inert single-walled carbon nanotube electrodes and embedding them into an optical microcavity.

The devices operate at 8 K, which is -265.15 degrees Celsius (-449.27 degrees Fahrenheit). The study, identified by DOI: 10.1038/s41586-026-10824-w, demonstrates a novel approach to laser diode construction using perovskite materials and carbon nanotubes.
