Layered Halide Perovskites In their Research Article (DOI: 10.1002/adma.202522768), Ji Tae Kim and co-workers demonstrate the freeform 3D fabrication of layered halide perovskite nanowire heterojunctions. By employing advanced direct printing techniques, the research team achieves precise spatial control and optimal crystallization of the layered perovskite structures at the micro/nano-scale. This versatile fabrication strategy opens new pathways for the direct monolithic integration of complex perovskite heterojunctions into next-generation high-performance optoelectronic devices.
