Abstract

The coefficients of thermal expansion (CTE) and elastic constants of single crystals of ZrB2 were discussed. Temperature ranges from room temperature to 1073 K and from room temperature to 1373 K. Results showed a small compressive stress in the GaN thin-films crystal growm on the (0001) surface of the ZnB2 substrate.
