science π¬ Hidden valleys boost perovskite electronics
Researchers found a way to control spin in 2D perovskites by creating hidden valleys. This was achieved by converting continuous spin textures into discrete states through local symmetry breaking. The study was published on September 1, 2026, in Nature Nanotechnology. This advancement unlocks long-lived, room-temperature spin control for optoelectronics. Future work will build upon this discovery for better electronic devices.
