Length-scale dependent average structures, piezoelectricity enhancement and depolarization mechanisms in a non-MPB high-performance piezoelectric alloy system PbTiO3-Bi(Zr1/2Ni1/2)O3
Rishikesh Pandey, Dipak Kumar Khatua, Shekhar Tyagi +4
There is a general perception that large piezoelectric response in ferroelectric alloys requires tuning the system towards a morphotropic phase boundary (MPB), i.e., a composition…
Correlation between structure and Rayleigh parameters in the lead-free piezoceramic (1-x)Ba(Ti0.88 Sn0.12)O3-x(Ba0.7Ca0.3)TiO3
Mulualem Abebe, Kumar Brajesh, Rajeev Ranjan
Composition dependent Rayleigh and structural analysis was carried out on the lead-free piezoceramics (1-x)(BaTi0.88Sn0.12)-x(Ba0.7Ca0.3)TiO3 at room temperature. The system exhibi…
A structural perspective on the origin of the anomalous weak-field piezoelectric response at the polymorphic phase boundaries of (Ba, Ca)(Ti, M)O3 lead-free piezoelectrics
Mulualem Abebe, Kumar Brajesh, Anupam Mishra +2
In this paper, we compare the structural features of Ca modified Ba(Ti, Sn)O3 with that of its Ca-free counterpart to understand why the Ca-modified variant of this lead-free piezo…
Extrinsic Rayleigh coefficient and domain mobility in critical MPB compositions of high-performance piezoceramics: A revisit
Mulualem Abebe, Rajeev Ranjan
Enhanced domain mobility is considered as one of the important characteristics of morphotropic phase boundary (MPB) ferroelectrics exhibiting a very large piezoelectric response. F…
