Fecha de publicación: | feb-2018 | Editor: | American Institute of Physics | Citación: | Applied Physics Letters, 112(5): Article number 051905 (2018) | Resumen: | The elastic constants of high-quality, single-crystal hexagonal boron nitride (h-BN) have been measured by means of high resolution Brillouin spectroscopy using a modified reflected light microscope. The sound propagation velocity in the c-axis direction and perpendicular to the c-axis have been obtained from the Brillouin frequency shift, with a proper account taken of the vast difference between the ordinary and extraordinary refractive indices recently reported in the highly anisotropic layered h-BN crystal. The elastic constants c11 and c33 obtained from the Brillouin experiments are somewhat lower than previous determinations based on inelastic x-ray measurements and confirm the overestimation of the h-BN elastic constants by ab initio calculations based on density functional perturbation theory in the local density approximation. | Versión del editor: | https://doi.org/10.1063/1.5019629 | URI: | http://hdl.handle.net/10261/160878 | DOI: | 10.1063/1.5019629 | ISSN: | 0003-6951 | E-ISSN: | 1077-3118 |
