“…Lin et al [25] reported the high dielectric tunabilities of (1 − x)BaZr 0.2 Ti 0.8 O 3 -xBa 0.7 Ca 0.3 TiO 3 (BZT-xBCT) (x = 0.15-0.55) thin films prepared by a sol-gel method. Wang et al [26] investigated infrared optical properties by infrared spectroscopic ellipsometry (IRSE) technique at room temperature of ferroelectric BZT-BCT sol-gel deposited thin films. Puli et al [2] demonstrated high dielectric breakdown, and excellent energy storage capacity in the (Ba 0.955 Ca 0.045 ) (Zr 0.17 Ti 0.83 )O 3 epitaxial thin films.…”

Lead-free 0.5BaZr0.2Ti0.8O3–0.5Ba0.7Ca0.3TiO3 (BZT–BCT) thin films were deposited on Pt(1 1 1)/TiO2/SiO2/Si substrates by pulsed laser deposition. The optimal ferroelectric response with a high saturation polarization Ps ~ 110 µC cm−2, remnant polarization Pr ~ 32.5 µC cm−2 along with a coercive field of 0.18 MV cm−1 was observed from the P–E hysteresis loops under an applied frequency of 1 kHz. A giant recoverable energy-storage density of 93.52 J cm−3 at an applied electric field ~3.47 MV cm−1 was observed. The optimized BZT–BCT thin films exhibited a high dielectric constant with a low dielectric loss at room temperature like their bulk counterpart (high dielectric constant (Ɛ ~ 121 81)) and low dielectric loss (tan δ ~ 0.01–0.03) properties. OPP-PFM images revealed switchable ferroelectric distinct polarization contrasts on the application of a ±12 V dc voltage on the conductive tip at room temperature. Observed enhanced dielectric, ferroelectric and energy density properties of BZT–BCT thin films are useful for next generation electrical energy storage applications.

Sol-gel-derived ferroelectric thin films, with lead zirconate titanate (Pb(Zr,Ti)O 3 , PZT) as one of the most widely studied materials, have been investigated for a wide range of applications, including microelectromechanical systems. The research of environment-friendly alternatives to lead-based materials, to a large extent driven by legislation, has been mainly conducted in the domain of bulk ceramics; however, environment-friendly alternatives to lead-based ferroelectric
