Temperature dependence of polarization and strain in Bi0.5Na0.5TiO3-SrTiO3 multilayer composites

Relaxor-ferroelectric phase transition materials exhibit excellent strain behavior under applied electric fields for utilization in actuator applications. However, the large strain of relaxor-ferroelectric phase transition materials can only be achieved in a narrow temperature range. Hence, in this study, composition-based multilayer samples and compositional gradient composite (CGC) samples were designed and fabricated to extend the usable...
