History-dependent and frequency-dependent dielectric nonlinearities induced by polar nanoregions in a thin film of 0.5 ( Ba 0.7 Ca 0.3 TiO 3 ) -- 0.5 ( BaZr 0.2 Ti 0.8 O 3 )

Kevin Nadaud, Guillaume Nataf, Nazir Jaber +3

In this article, dielectric nonlinearities in 0.5(Ba0.7 Ca0.3 TiO3 ) -- 0.5(BaZr 0.2 Ti0.8 O3 ) thin film are studied using impedance spectroscopy and harmonic measurements, as a f…

Evidence of the matrix effect on a compositionally graded oxide thin film

J. Scola, F. Jomard, E. Loire +4

A heterostructure of Ba $_{1 - x}$ Sr $_{x}$ TiO $_{3}$ /La $_{1.1}$ Sr $_{0.9}$ NiO $_{3}$ /SrTiO $_{3}$ has been analysed by magnetic sector secondary ion mass spectrometry (SIMS). The stoichiometry p…

Enhancement of piezoelectric properties in a narrow cerium doping range of $Ba_{1 - x} Ca_{x} Ti_{1 - y} Zr_{y} O_{3}$ evidenced by high throughput experiment

Kevin Nadaud, Guillaume F. Nataf, Nazir Jaber +5

Lead-free materials based on the $(Ba,Ca)(Zr,Ti)O_{3}$ (BCZT) system exhibit excellent electromechanical properties that can be strongly modified by small amounts of dopants…
