Method and system micromechanical exfoliation dry process of two-dimensional sheet materials

摘要

Method and system micromechanical exfoliation by dry sheet materials. # The method comprises contacting a flat face (Lp) of a sheet material bidimensional (L) with a flat face (Sp) of a substrate (S) and exert force between them, according to a direction normal to the plane defined by said planar face (Lp) of said sheet material bidimensional (L), in a controlled manner, and thereafter, applying a motion shear controlled between said flat faces (Lp, Sp ) of the sheet material bidimensional (L) and the substrate (s), producing delamination, i.e. the delamination of an ultrathin layer of laminate bidimensional (L) and its deposition on the substrate (s). # the system is adapted to implement the method of the invention.
