Elasticity of hexagonal boron nitride: Inelastic x-ray scattering measurements

Abstract:

The five independent elastic moduli of single-crystalline hexagonal boron nitride (h -BN) are determined using inelastic x-ray scattering. At room temperature the elastic moduli are in units of GPa C11 =811, C12 =169, C13 =0, C33 =27.0, and C44 =7.7. Our experimental results are compared with pbkp_redictions of ab initio calculations and previously reported incomplete datasets. These results provide solid background for further theoretical advances and quantitative input to model elasticity in boron nitride (BN) nanotubes. © 2006 The American Physical Society.
