摘要：
The elastic deformation of few layers ( 5 to 25) of thick, freely suspended MoS2 nanosheets by means of a nanoscopic version of a bending test experiment, carried out with the tip of an atomic force microscope is reported. Young's modulus of these nanosheets is extremely high ( E = 0.33 TPa), comparable to that of graphene oxide, and the deformations are reversible up to tens of nanometers.
