  Uniaxial tensile properties of hexagonal boron nitride nanoribbons and
dependence of these properties on temperature, strain rate, and the inclusion
of vacancy defects have been explored with molecular dynamics simulations using
Tersoff potential. The ultimate tensile strength of pristine hexagonal boron
nitride nanoribbon of 26 nm x 5 nm with armchair chirality is found to be 100.5
GPa. The ultimate tensile strength and strain have been found decreasing with
increasing the temperature while an opposite trend has been observed for
increasing the strain rate. Furthermore, the vacancy defects reduce ultimate
tensile strength and strain where the effect of bi-vacancy is clearly
dominating over point vacancy.
