Silicon Carbide: A Tug-Of-War - EE Times India

Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”

Gallium Orthophosphate - FAQs

For Gallium Orthophosphate shear cuts you can use the piezoelectric constant d 26.It shows the same perfect thermal stability as d 11 but twice the sensitivity (d 26 = -2d 11). When you are used to manufacturing transducers with LiNbO 3, LiTaO 3 (both point group "3m") or ceramics ("6mm"), the values for d 11 and d 14 are zero, so you have to use the d 15 for X-cut or Y-cut shear mode.
