Elastic properties and tensile strength of 2D Ti₃C₂T_x MXene monolayers.

ABSTRACT: Two-dimensional (2D) transition metal nitrides and carbides (MXenes), represented by Ti₃C₂T_x, have broad applications in flexible electronics, electromechanical devices, and structural membranes due to their unique physical and chemical properties. Despite the Young's modulus of 2D Ti₃C₂T_x has been theoretically predicted to be 0.502 TPa, which has not been experimentally confirmed so far due to the measurement is extremely restricted. Here, by optimizing the sample preparation, cutting, and transfer protocols, we perform the direct in-situ tensile tests on monolayer Ti₃C₂T_x nanosheets using nanomechanical push-to-pull equipment under a scanning electron microscope. The effective Young's modu
