Abstract
Size-dependent piezoelectric coefficient d33(D) (D shows particle diameter) for small ferroelectrics is modeled in this paper. It is found that taking account of size effect is essential in understanding piezoelectric characteristics of nanoferroelectrics. The model prediction is in good agreement with the experimental results for PbTiO3nanoparticles, where d33(D) increases correspondingly as D decreases.
