Developing novel lead-free ferroelectrics is still a challenging task. In their article on pp. 1035–1040, Z.G. Yi et al. from the Shanghai Institute of Ceramics, China, and Australian National University, Canberra, show a two-step materials design strategy: (1) fabricating intergrowth ferroelectric structures, followed by (2) Bi-site engineering. The interesting ferroelectricity thus obtained is also discussed. The ferroelectric and piezoelectric properties of La-doped Bi5TiNbO15 and Bi7Ti4NbO21 ceramics are studied in detail.
This article forms part of the Special Section “Advances in Electronic Materials and Devices in the Far East”, guest edited by Giuseppe Pezzotti (see also the Preface on pp. 971–974).
