Atomic-level engineering of perovskite materials opens the way to new lasers and LEDs
Graphical summary. Credit: Matter (2024). DOI: 10.1016/j.matt.2024.09.010 Researchers have developed and demonstrated a technique that can process a class of materials called layered hybrid perovskites (LHPs) down to the atomic level. This determines exactly how the material converts electrical charge into light. This technology opens the door to engineering materials for use in next-generation printed LEDs and lasers, and is…
