Extended Data Fig. 2

Schematic assignment of the GIWAXS patterns, suggesting that the 2D perovskites are mainly horizontally oriented. The strong Bragg spots suggest that the 3D perovskite has a highly-ordered and vertically-orientated crystal packing. The incident angles (α) of 0.1° and 0.3° corresponds to the penetration depth of 3-5 nm and > 100 nm, respectively.
