Kinetic retention of an anisotropic lattice response in pure FAPbI₃ by flash infrared annealing

Far-from-equilibrium crystallization can access metastable states absent from equilibrium phase diagrams, but using the processing trajectory to select such states in functional semiconductors remains underexplored in halide perovskites. Here we examine pure formamidinium lead iodide (FAPbI₃), whose photoactive structu...
