We study the elastic deformation of few layers (5 to 25) 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. The Young's
modulus of these nanosheets is extremely high (E = 0.33 TPa), comparable to
that of graphene oxide, and the deflections are reversible up to tens of
nanometers.
