Flux growth of (Pb,La)(Zr, Sn,Ti)O3 single crystals and their characterization

“…This class of materials has been extensively studied for their potential applications in actuation, energy conversion and charge storage [1][2][3][4]. However, up to now all the investigations were performed on polycrystalline PLZST samples [5][6][7][8][9][10], and their practical use was limited to sintered ceramics consisting of randomly oriented crystal grains. If the appropriate axis is utilized, single crystals generally have superior properties than the polycrystalline ceramics, for example PMN-PT [11][12][13], PZN-PT [14][15][16] However, few studies have reported PLZST single crystal growth to our knowledge.…”

Enhancement of energy storage in epitaxial PbZrO3 antiferroelectric films using strain engineering

“…Earlier research on Pb(Zr 1ÀxÀy Sn x Ti y )O 3 (PZST) films showed tensile strains would make the AFE films prone to the FE phase by observing a "slim loop" double hysteresis. 12,13 However, recent studies argued compressive strain could stabilize a FE phase in (001) pc -epitaxial PbZrO 3 thin films 14 and multilayer PZST films. 15 Recent theory calculations have suggested that AFE phase stability with strain is also related to the growth orientation of AFE films 16 and has been proven by experimental results from highly oriented polycrystalline PbZrO 3 films.…”

Effect of residual stress on energy storage property in PbZrO3 antiferroelectric thin films with different orientations

“…Xu et al studied the field-induced phase switching of (111)-oriented lead zirconate titanate stannate (PZST) thick films on Si substrate and concluded that the tensile stress due to the thermal mismatch between film and substrate would make the films prone to the FE phase. 14,15 However, it appears that no report on strain dependency of AFE films on different substrates has been published. Hence, in this study, PbZrO 3 thin films, which are the prototype of AFE films, were deposited on LaNiO 3 (LNO) buffered SrTiO 3 and SiO 2 /Si substrates and their strain-induced structure property and energy storage property as a function of temperature have been investigated.…”
