Description:
(abstract)The arrangement of unilamellar 2D nanosheets on a substrate surface, avoiding large gaps and overlaps, is crucial for fully harnessing their performance. A resulting monolayer film of neatly tiled 2D nanosheets can provide a molecularly thin interface and a well-defined crystalline surface, leading to the development of unique properties and reactivities. Consequently, considerable efforts have been focused on developing solution-based assembly techniques, including electrostatic self-assembly, the Langmuir-Blodgett (LB) method, and spin coating, to produce highly organized monolayer films.
Neatly tiled monolayer films of nanosheets have been applied to modify the surface and interface properties of materials, as exemplified by the performance enhancement of batteries and epitaxial growth of crystalline thin films. Furthermore, the precise monolayer tiling serves as the fundamental step for constructing multilayer films of each nanosheet or even artificial lattice-like films, where nanosheets are stacked in a designed sequence, allowing for the evolution of sophisticated functionalities via synergetic coupling between constituent nanosheets. It has been demonstrated that heterostructured films, composed of various types of nanosheets, can enhance the individual properties of components and introduce novel functions. The integration of nanosheets with different properties using the methods outlined in this Account will lead to the realization of various next-generation devices.
