An organic-inorganic perovskite ferroelectric with large piezoelectric response
2017
Science
Molecular piezoelectrics are highly desirable for their easy and environment-friendly processing, light weight, low processing temperature, and mechanical flexibility. However, although 136 years have passed since the discovery in 1880 of the piezoelectric effect, molecular piezoelectrics with a piezoelectric coefficient d 33 comparable with piezoceramics such as barium titanate (BTO;~190 picocoulombs per newton) have not been found. We show that trimethylchloromethyl ammonium
