A polytype transformation was observed through a significant increase in the 6H–SiC phase at compressive stresses higher than 4.5 GPa (in the vicinity of the dynamic compressive failure strength).

Chemical Properties of Oxidized Silicon Carbide …

The present work shows that HF etching of oxidized silicon carbide (SiC) leads to a very different surface termination, whether the surface is carbon or silicon terminated. Specifically, the silicon carbide surfaces are hydrophilic with hydroxyl termination, resulting from the inability of HF to remove the last oxygen layer at the oxide/SiC interface.
