Abstract
The complete sets of elastic constants of 4H and 6H silicon carbide si ngle crystals were determined by Brillouin scattering. The elastic con stants of 6H SiC are C-11=501+/-4, C-33-553+/-4, C-44=163+/-4, C-12=11 1+/-5, and C-13=52+/-9 GPa; the corresponding ones of 4H SiC are the s ame within experimental uncertainties. The compressibility, 4.5x10(-3) GPa, is about 3-5 times smaller than those reported for polycrystalli ne SiC materials. (C) 1997 American Institute of Physics.
