“…Ceramic targets of KNLNS-BCZ and KNLNS-BBNZ of 20 mm in diameter were prepared by conventional solid-state method. Detailed procedure and more information regarding the target's preparation of KNLNS-BCZ and KNLNS-BBNZ are reported elsewhere [9,10]. Thin films of KNLNS-BCZ and KNLNS-BBNZ were deposited on Pt/TiO2/SiO2/Si substrates by pulsed laser deposition (PLD) using a KrF Excimer laser (λ=248 nm).…”

In thiswork, 0.96(K0.48Na0.52)0.95Li0.05Nb0.94Sb0.06O3-0.04Ba0.94Ca0.06ZrO3 (KNLNS-BCZ) and 0.98(K0.48Na0.52)0.95Li0.05Nb0.95Sb0.05O3-0.02Ba0.5(Bi0.5Na0.5)0.5ZrO3 (KNLNS-BBNZ) ferroelectric thin films were obtained by pulsed laser deposition. The structural, and morphological characteristics were studied to determine the best deposition parameters and analyse the piezoelectric properties. The studied deposition parameters were temperature, laser fluence, oxygen partial pressure and frequency. These parameters impact important characteristics of the thin films like grain morphology, thickness, and roughness. KNLNS-BCZ thin films with pure perovskite structure, homogeneous grain growth, and thickness ≥100 nm were fabricated at 700 °C, 2 J/cm 2 , 300 mTorr, and frequencies of 5 Hz and 10 Hz. These films presented good ferroelectric behaviour and piezoelectric coefficient d33eff of 83.80 pm/V and 25.80 pm/V, respectively.

Effect of Antimony Content on Transition Behavior and Electric Properties of (K0.44Na0.52Li0.04)(Nb0.9−xTa0.10Sbx)O3 Ceramics

Here, (K0.44Na0.52Li0.04)(Nb0.9−xTa0.1Sbx)O3 [KNL−(N0.9−xTSx)] lead-free ceramics with potential technological applications are made through B-position substitution on the perovskite structure by Sb ions. This strategy generates crystal structure changes and stabilizes a tetragonal symmetry, T, giving place to an orthorhombic (O–T) phase boundary close to room temperature. Specifically, our results establish that an increase in relative volume fractions of the T on the O–T phase boundary produces an increase in functional properties. More relevantly, this improvement in properties is accompanied by controlling the grain size. Therefore, an increase in grain size promotes the increased domain size, favoring more domain wall motion and domain switching. Both effects result in an increase in the d33 coefficient. Finally, we believe this work helps to understand the factors that determine the improvement in the functional properties of the KNN–based piezoelectric ceramics.
