Description
A model that predicts the macro-scale temperature-dependent interfacial shear strength of 2D materials like MoS2 based on atomistic mechanisms and energetic barriers to sliding has been developed. Atomistic simulations were used to systematically determine the lamellar size-dependent rotation and translation energy barriers, that were used to accurately predict a broad range of experimental data. This framework provides insights about the origins of characteristic shear strengths of 2D materials.
