(a) An AFM height image of a suspended flake ( layers). (b) Schematic overview of the method used to determine the local compliance of the flake. (c) Two linear force-distance curves (offset for clarity) taken on the flake shown in (a). The approaching (gray) and retracting (black) parts of the curves lie on top of each other. The bottom curve is taken on an unsuspended part of the flake, while the top curve is taken on a suspended part.
(a) Color map of the compliance of a flake with , extracted from a force-volume measurement ( force-distance curves). The compliance ranges from 0 (blue) to (orange). (b) The calculated deflection in the absence of tension for a force applied at the position of the cross. (c) The measured radial profile of the compliance (symbols) of a thick flake and the fit by the model (solid line). (d) The radial profile of the data shown in (a).
Thickness dependence of the mechanical properties extracted from the fits. (a) The bending rigidity (symbols) and the continuum relation (gray line). (b) The tension in the flake . (c) The frequency of the fundamental mode calculated with the measured values for and for two different hole sizes. The inset shows the displacement profile of this mode.
