I read that galium nitride and silicon carbide are piezo materials.Does this cause some problems? I can imagine that unwanted piezoelectricity directly in the circuit path would cause some kind of distortion or noise.
Can this be modeled as some kind of parasitic voltage source? How strong is this effect? I know some piezoelectric materials are alot more piezoelectric than others,is SiC and GaN only extremly weak piezoelectric materials ,so weak that it can be ignored?
