Defect Engineering of BCZT–based Piezoelectric Ceramics with High Piezoelectric Properties [PDF]

open access: yesJournal of Advanced Ceramics, 2021
Abstract The intrinsic conduction mechanism and optimal sintering atmosphere of (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) ceramics was regulated by doping Mn element in this work. By Hall and impedance analysis, the undoped BCZT ceramics exhibit a typical n–type conduction mechanism, and the electron concentration decreases with the increasing oxygen
