Abstract

Growth, microstructure, and ferroelectric properties of Pb ( Zr 0.4 Ti 0.6 ) O 3 ∕ Pb Zr O 3 superlattices prepared on Sr Ti O 3 (100) substrates by pulsed laser deposition Field-induced dielectric properties of laser ablated antiferroelectric ( Pb 0.99 Nb 0.02 )(Zr 0.57 Sn 0.38 Ti 0.05 ) 0.98 O 3 thin films

Structure and electrical properties of PbZrO3 antiferroelectric thin films doped with barium and strontium

“…PbZrO3, (Pb0.95Ba0.05)ZrO3 [PBZ (5) [18,19]. Barium acetate (99.5%, Sinopharm Chemical Reagent Co., Ltd., China), strontium acetate (99.9%, Sinopharm Chemical Reagent Co., Ltd., China), lead acetate trihydrate (99.5%, Sinopharm Chemical Reagent Co., Ltd., China) and zirconium isopropoxide (70% in propanol, Aldrich) were used as raw materials.…”

“…Hence, AFE materials have potential applications in micro-actuators, IR-detectors, digital memories, high energy storage capacitors and cooling devices [1][2][3][4]. Pure PbZrO 3 (PZ) with a Curie point of 230 • C is the most stable AFE material at room temperature [5]. PZ-based materials in bulk and film forms are also the most extensively investigated AFE materials at present.…”

Theoretical study of ion doping and substrate effects in antiferroelectric thin films

“…Such PZ thin films, epitaxially grown on MgO substrates, achieves high dielectric constants which are nearly 2.4 times larger than that of bulk PZ [15]. Chattopadhyay et al [18] investigated PZ thin films on Si(100) substrates. They found an AFE [19].…”

Antiferroelectric thin films phase diagrams

“…Ayyub et al [7] have shown that a typically antiferroelectric material PbZrO 3 or BiNbO 4 displays ferroelectric behavior below a critical film thickness characteristic of the system. Namely, 100nm PbZrO 3 /Si film has ferroelectric hysteresis loop, whereas 900 nm film posses the antiferroelectric one.…”

“…Chattopadhyay et al [3] demonstrated that thin PbZrO 3 films on Si substrate possess switchable polarization. Hung et al [4] have found that multilayer of PbZrO 3 /BaZrO 3 has ferroelectric properties.…”
