Research Reveals Unusual Doping Effect in High Curie Temperature Piezoelectric Ceramics

Piezoelectric ceramics with a working temperature higher than that of the conventional Pb(Zr,Ti)O3 (PZT) have recently attracted increasing attention. High Tc and high piezoelectric response were recently achieved for a new perovskite type sy...
