From defects to order: Spontaneously emerging crystal arrangements in perovskite halides Perovskites are among the most extensively studied materials in modern materials science. Their often unique and exotic properties, which stem from perovskite's peculiar crystal structure, could find revolutionary applications in various cutting-edge fields. One intriguing way of realizing such properties is through the precise ordering of a perovskite's defects, such as vacancies or substitutions.
