The shear stiffness of carbon nanotubes was measured using a modified AFM. The technique uses a laterally vibrating tip to produce a shearing effect as the tip is rastered over substrate and sample. The amplitude of the lateral oscillations allows an indirect measurement by comparing the response of the substrate and sample. The substrate and sample were placed on a rotating stage to obtain a sequence of amplitude images of a nanotube in various orientations.
