Ferroelectric thin‐film capacitors are of interest for energy storage due to their high charge/discharge rates, essential compact electronics. As alternatives Pb‐based materials, environmentally friendly barium titanate–based systems show great energy‐storage potential. Herein, Ba 0.7 Sr 0.3 TiO 3 (BST7)/Ba 0.6 0.4 (BST6) thin films altering the layer structure designed and constructed on boron‐doped Si <100> substrates by solution‐based spin‐coating method. The structural electric properties trilayer investigated, results compared with those monolayer such as BST7 BST6. An enhanced polarization improved breakdown strength simultaneously achieved in BST767 (Ba /Ba ) film caused interfacial effect, which leads an ultrahigh density ( W rec ≈56.9 J cm −3 accompanying efficiency η ≈72%. capacitor processes a fast charging/discharging speed giant power 0.72 MW . These exhibit relatively resistive switching behavior on–off ratio ceramic capacitors. mechanisms underlying current conduction thoroughly analyzed. Such performance makes them suitable future portable electronics, hybrid vehicles, aerospace applications.
