Extended Data Fig. 5: The NMP design.
From: A fabrication process for flexible single-crystal perovskite devices
a, Schematics for calculating the position of the NMP. The SU-8/PDMS top layer is critical for minimizing the strain in the single-crystal perovskite layer. b, Optical (left) and SEM (right) images under different bending conditions. The single-crystal perovskite (about 2 μm thick) can be successfully bent to r ≈ 2.5 mm. All optical images share the same scale bar. All SEM images share the same scale bar.
