What is the best for piezoelectric material?

[ralden]

Based on my research the effects of the holes, electrons, acceptor and donor concentration is telling you the direction of the polarization and the conventional sign of the electric potential generated. But up until now, i don't know what is the best material to used for piezoelectric material. is it n-type or p-type semiconductor ?(assuming that this semiconductor have high piezoelectric coefficient). Is conductivity and resistivity affects the generated potential? if so please enlighten me and send me a link about your reference papers! thank you!

The best material to use for piezoelectric materials is a piezoelectric material. Piezoelectric materials are materials that can generate electrical potential when subjected to mechanical stress. Common piezoelectric materials include quartz, Rochelle salt, and polyvinylidene fluoride (PVDF). These materials are typically non-conductive and have no effect on the generated potential. However, conductivity and resistivity may affect the amount of charge stored in the piezoelectric material and thus the amount of potential generated. Conductivity is a measure of how well a material allows electricity to flow through it, while resistivity is a measure of how difficult it is for electricity to flow through the material. Materials with higher conductivity will allow more charge to be stored and thus more potential to be generated.For more information on the properties of piezoelectric materials and how they affect the generated potential, please see the following articles:1.
