Large Piezoelectric Effect in Pb-Free Ceramics
TL;DR: It is predicted that the single-crystal form of the MPB composition of the present system may reach a giant d(33) = 1500-2000 pC/N, which may provide a new recipe for designing highly piezoelectric materials (both Pb-free and P b-containing) by searching MPBs starting from a TCP.
