Perovskite Films: Iodine Vacancy Redistribution in Organic–Inorganic Halide Perovskite Films and Resistive Switching Effects (Adv. Mater. 29/2017)

Perovskite Films: Iodine Vacancy Redistribution in Organic–Inorganic Halide Perovskite Films and Resistive Switching Effects (Adv. Mater. 29/2017)
Xiaojian Zhu, Wei D. Lu, Jihang Lee
Understanding and controlling defect generation and movement in organic-inorganic lead halide perovskite materials will not only lead to more stable devices but also new device concepts. In article number 1700527, Wei D. Lu and co-workers reveal the formation, migration and annihilation of iodine vacancies in CH3NH3PbI3 films under an electric field and/or light illumination. An electric-write and light-erase memory device is demonstrated.
