Simultaneously enhanced energy density and discharge efficiency of (Na0.5Bi0.5)0.7Sr0.3TiO3-La1/3(Ta0.5Nb0.5)O3 lead-free energy storage ceramics via grain inhibition and dielectric peak flattening engineering

“…13,14 However, the low efficiency caused by the large P r limits the actual application of BNT-based ferroelectrics. 1 Commonly, forming multivariate solid solution systems is a feasible modification approach for BNT-based ceramics to obtain relatively superior ESP, such as (1 − x )Bi 0.5 Na 0.5 TiO 3 - x BaTiO 3 , 15–17 (1 − x )Bi 0.5 Na 0.5 TiO 3 - x NaNbO 3 , 18,19 (1 − x )Bi 0.5 Na 0.5 TiO 3 - x CaTiO 3 20,21 and (1 − x )Bi 0.5 Na 0.5 TiO 3 - x SrTiO 3 (BNT-ST). 22,23 In particular, BNT-ST is considered as one of the most potentially useful energy storage ceramic materials as it can decrease the temperature at the dielectric maxima ( T m ) and exhibit a thinner P – E loop and lower P r under low E conditions.…”

Self-Powered High-Responsivity Photodetectors Enhanced by the Pyro-Phototronic Effect Based on a BaTiO3/GaN Heterojunction

“…As one of the most widely investigated perovskite materials, BaTiO 3 (BTO) has been commonly applied in various fields, including electrocaloric refrigeration, − energy storage, − dielectric tuning, , and various sensing. − Because of the multifarious physical characteristics owned by BTO, such as ferroelectric, , piezoelectric, , thermoelectric, , pyroelectric, , and photovoltaic properties, − there has been significant progress in the conversion from light, heat, and pressure to an electrical signal. Furthermore, it is this kind of mutual coupling of various characteristics that overcomes the disadvantages caused by only single-source conversion in the past.…”

Fascinating Electrical Transport Behavior of Topological Insulator Bi2Te3 Nanorods: Toward Electrically Responsive Smart Materials

“…[26][27][28][29] However, most voltage-controlled nonlinear electronic materials are limited by uncertainty about the voltage dependence of resistance or require a large bias voltage to overcome. For example, ferroelectric materials, as a kind of voltage-controlled nonlinear electronic material, [30][31][32] are difficult to achieve the same resistivity at same electric field due to hysteresis loops. Therefore, it is essential to find a material with monotonic electrical response for the applications in smart microelectronic devices or circuits.…”
