Nanosheet

[10] The formation of free-floating CdTe nanosheets was due to directional hydrophobic attraction and anisotropic electrostatic interactions caused by dipole moment and small positive charges.

Molecular simulations through a coarse-grained model with parameters from semi-empirical quantum mechanics calculations can be used to prove the experimental process.

Ultrathin single-crystal PbS (lead sulfur) sheets with micro scale in x-, y- dimensions can be obtained using a hot colloidal synthesis method.

For instance, hexagonal PbO (lead oxide)) nanosheets were synthesized using gold nanoparticles as seeds under room temperature.

Oriented attachment, in which the sheets form by aggregation of small nanoparticles that each has a net dipole moment,[12][13] and ostwald ripening[14] are the two main reasons for the formation of the PbO nanosheets.
