Thickness control and flexibility of (PEA)2PbI4 SCMs. a 3D AFM image of a (PEA)2PbI4 SCM and b height profile of the line scan. c Cross-sectional SEM images of the (PEA)2PbI4 SCMs with different thicknesses (0.6, 12, 34, 47 μm). d Photo of a piece of (PEA)2PbI4 SCM, 3.5 μm in thickness, wrapped around a small tube (1.6 cm in diameter) to show its flexibility. e A photo showing the flexing angle measurement for the (PEA)2PbI4 SCM. f Correlation of the (PEA)2PbI4 SCM thickness and corresponding flexing angle, with the insets showing cross-sectional SEM images of the (PEA)2PbI4 SCMs with three thicknesses (7.14, 20.48, 30.56 μm)
