In article number 2011093, Youngjong Kang and co‐workers present a simple in situ quenching‐assisted fabrication technique for FA m +2 Pb m Br 3 m +2 films possessing wide dimensional controllability from 1D to 3D structures. The FA m +2 Pb m Br 3 m +2 exhibits an unusual (110)‐oriented structure that shows a phase transition to 3D FAPbBr 3 under humidity and ultra‐violet light exposure. The phase transition behavior of FA m +2 Pb m Br 3 m +2 is utilized for the phase‐change memory films.
