## Description

- description: Neat (dense and non-overlapped) monolayer tiling of 2D nanosheets on
    a substrate surface is very important because we can conduct artificial lattice-engineering
    by repeating the tiling process in a designed sequence to tailor various hierarchical
    nanostructures, leading to a range of sophisticated functions. It is recently
    reported that a facile spin-coating technique realizes the neat monolayer tiling
    of various 2D nanosheets. Establishing universal guidelines to neatly tile 2D
    nanosheets on substrates of various materials and size/shape is of essential importance
    to fully apply this technique, but the mechanism how the nanosheets are tiled
    has not been clarified yet. In the present study, we have systematically examined
    the nanosheet deposition process at various rotation speeds by microscopic observations
    and found that the neat monolayer tiling of nanosheets is attained on the solvent
    surface during the spin-coating, and then the monolayer film is deposited onto
    the substrate surface from its center toward the edges upon evaporation of the
    solvent. Furthermore, we have clarified how the rotation speed and the nanosheet
    concentration govern the deposition behaviors in terms of neat tiling, overlap,
    or non-coverage in a such process. On the basis of the guidelines, we can predict
    the optimum spin-coating conditions for attaining the neat monolayer tiling of
    various nanosheets over an entire surface of the substrate.
