Elastic Properties of Freely Suspended MoS2 Nanosheets

Elastic Properties of Freely Suspended MoS2 Nanosheets

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), com...

Zusammenfassung: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.
