Abstract

Vertically oriented highly crystalline 2D layered (BA) 2 (MA) n −1 Pb n I 3 n +1 (BA = CH 3 (CH 2 ) 3 NH 3 , MA = CH 3 NH 3 , n = 3, 4) perovskite thin‐films are fabricated with the aid of ammonium thiocyanate (NH 4 SCN) additive through one‐step spin‐coating process. The humidity‐stability of the f...
