Cubic or orthorhombic? Revealing the crystal structure of metastable black-phase CsPbI3 by theory and experiment
Room-temperature films of black-phase cesium lead iodide (CsPbI3) are widely thought to be trapped in a cubic perovskite polymorph. Here, we challenge this assumption. We present structural refinement of room-temperature black-phase CsPbI3 in an orthorhombic polymorph. We demonstrate that this polym...
