A modified Stillinger–Weber empirical potential for boron nitride

We have proposed the parameters of the Stillinger–Weber potential for boron nitride. The structural properties and the elastic constant of boron nitride have been investigated using molecular-dynamics simulation. The thermodynamics properties, such as thermal expansion coefficient and specific heat, have also been calculated. These results are in agreement with other theoretical data and experiments. This shows the availability of this potential to investigate physical properties of boron nitride
