  We report results on the Young's modulus (YM) of defect-free and defective
silicene nanoribbons (SNRs) as a function of length and temperature. In this
study, we perform molecular dynamics simulations using the
Environment-Dependent Interatomic Potential (EDIP) to describe the interaction
of the Si atoms. We find that the Young's modulus of pristine and defective
SNRs increases with the ribbon length in both chirality directions. It is shown
that the Young's modulus of defective SNRs exhibit a complex dependence on the
combinations of vacancies. With respect to temperature, we find that YM for
SNRs with and without vacancy defects shows a nonlinear behavior and it could
be tailoring for a given length and chirality.
