Since the discovery of Rochelle salt a century ago, ferroelectric materials have been
investigated extensively due to their robust responses to electric, mechanical, thermal …

We present a critical review that encompasses the fundamentals and state-of-the-art
knowledge of barium titanate-based piezoelectrics. First, the essential crystallography …

Electric field-induced transformations occur in a myriad of systems with a variegated
phenomenology and have attracted widespread scientific interest due to their importance in …

There is great interest in lead-free (B a 0.85 C a 0.15)(T i 0.90 Z r 0.10) O 3 (15/10BCTZ)
because of its exceptionally large piezoelectric response [Liu and Ren, Phys. Rev. Lett. 103 …

The structural complexities of the lead-free piezoelectric system (1-x) Na 0.5 Bi 0.5 TiO 3-x
BaTiO 3 (NBT-BT) continues to pose challenge regarding understanding the mechanisms …

The functional properties of a series of BaTiO 3 ceramics, having grain sizes ranging from 75
nm to 2.25 μm, with polymorph coexistence around room temperature are presented. Large …

The demand for high-performance lead-free piezoelectric materials towards mechanical
energy harvesting has been driven by the continuous requirements of self-powered …

Phase transition describes a mutational behavior of matter states at a critical transition
temperature or external field. Despite the phase-transition orders are well sorted by classic …

We show that an electrically soft ferroelectric host can be used to tune the
photoluminescence (PL) response of rare-earth emitter ions by external electric field. The …

Driven by environmental concerns and governmental directives, a sustained research effort
in the last decade and half has led to the development of lead-free alternatives which can …
