Fabrication of Flat and Smooth Lead-Based Layered Perovskite Films at a Transfer Process of the Langmuir-Blodgett Method

Abstract: This paper presents a novel approach for fabricating lead-based layered perovskite films. The perovskite structure was formed during the transfer of a perovskite-unform monolayer onto a substrate. The transferred film had a flat and smooth surface, and the surface roughness was greatly improved from 5.5 nm to 1.8 nm, compared to the transferred film of a perovskite-form monolayer on the water.

“…However, its applicability is not limited to these typical film components. Thin film organizations were actually demonstrated for various nanomaterials, 42 two-dimensional materials, 43 and biomaterials such as proteins 44 using the LB technique. Furthermore, forefront objects such as supramolecular polymers, 45 DNA origami pieces, 46 molecular machines, 47 and artificial receptors 48 can be subjected to the LB technique.…”

“…For example, the Langmuir–Blodgett (LB) method [ 95 96 ] and layer-by-layer (LbL) assembly [ 97 98 ] are used to organize materials from molecules. Oishi and co-workers have used the LB method to create layered perovskite films with a uniform surface [ 99 ]. Similarly, LbL assembly is a simple and convenient way to create a wide range of materials in a designed layered structure.…”

“…Compared to materials fabrication by self-assembly, which relies on simple equilibrium processes, nanoarchitectonics is advantageous in forming asymmetric and hierarchical structures [ 48 ] because it often incorporates several processes, including equilibrium and nonequilibrium ones. For example, various unit processes such as self-assembly [ 49 , 50 , 51 ], template syntheses [ 52 , 53 , 54 ] can be combined with thin films using methods such as the Langmuir-Blodgett (LB) method [ 55 , 56 , 57 ] or layer-by-layer (LbL) assembly [ 58 , 59 , 60 ]. Through molecular self-assembly together with template synthesis, synthesized nanomaterials can be immobilized on device surfaces as hierarchical thin films using these methods [ 61 , 62 ].…”
