Comparative analysis for the crystalline and ferroelectric properties of Pb(Zr,Ti)O3 thin films deposited on metallic LaNiO3 and Pt electrodes

BaTiO3 on LaNiO3 and Si thin films prepared by mist plasma evaporation

“…The grain size of the BTO film on LNO electrode was about 130 nm, which was smaller than 180 nm of the BTO film on Pt electrode. This was consistent with the literature [18], and Chae et al also found that the grain size of the PZT film deposited on LNO electrode was smaller than that of the film on Pt electrode [13]. of the BTO/LNO film showed obvious frequency dependence.…”

“…Particularly, highly textured PZT films were obtained on (1 0 0)-oriented LNO substrates by the sol-gel technique and showed great improvement in polarization fatigue [9]. At present, many preparation techniques, such as pulsed laser deposition (PLD) [8], metalorganic decomposition (MOD) [10], sol-gel [11], RF magnetron sputtering [12,13] have been used to prepare ferroelectric thin films on perovskite oxides bottom electrodes. Recently, mist plasma evaporation (MPE) has been developed by us to prepare ferroelectric thin films.…”

Ferroelectric and structural instability of (Pb,Ca)TiO3 thin films prepared in an oxygen atmosphere and deposited on LSCO thin films which act as a buffer layer

“…These authors reported that BST thin films with LSCO buffer layers had a smoother surface and a smaller grain size than thin film buffer layers on Pt substrates. Chae et al [37] researched PZT thin films grown on Pt/Ti/SiO 2 /Si substrates with and without LaNiO 3 (LNO) buffers layers by the sol-gel technique and revealed that the PZT thin film average grain size on LNO buffers layers is smaller than that of the grain size on metal electrode (platinum substrate) films; this result is consistent with our results.…”

Residual stress of Pb(ZrxTi1−x)O3 films with mixed textures

“…Because the lattice mismatch of the atom arrangements between (1 1 1) plane of PZT and (1 1 1) plane of Pt is only 2.8% [20], (1 1 1) texture in PZT film can be induced by (1 1 1) oriented Pt substrate. In addition, (1 0 0) texture has also been found on (1 1 1)-oriented Pt substrate by some authors [21][22][23], which suggests that the (1 0 0) PZT //(1 1 1) Pt is possible in point of interface energy.…”
