This breakthrough demonstrates the first electrically pumped perovskite polariton laser diode, overcoming decades-long barriers in solution-processed semiconductor physics. By leveraging exciton-polaritons within an optical microcavity to achieve Bose-Einstein condensation at lower energy densities, this development paves the way for inexpensive, high-speed neuromorphic computing and efficient optical sensing without relying on complex epitaxial growth or suffering from severe heat accumulation.
Researchers Demonstrate 1st Electrically Pumped Perovskite Polariton Laser Diode

Resolving a long-standing problem in semiconductor physics and optoelectronics, a team of researchers from Skoltech — a VEB.RF group institution — and their colleagues from ITMO University and HSE University have for the first time demonstrated direct electrical pumping of a polariton laser based on a solution-processed halide perovskite microcrystal. Published in Nature, this solution to a decades-long technological challenge ushers in inexpensive…
