a Landau energy profile of the matrix components. Comparative display of the (b) intensity mapping of B-site of the perovskite at atomic scale; c height and density of transport barriers along electric field direction L, with Ea being the activation energy of charge carriers; and (d) band structure based on experiment and density function theory (DFT) calculation, highlighting the conduction band minimum (CBM), valence band maximum (VBM) and band gap energy (Eg). e Self-assembled twofold crystal superstructure of NN-xCHZS. f Electrical microstructure enhancement of one order of magnitude. g Elevated operating voltage and energy density of capacitors for traction invertor in electric vehicles (EVs) with the high entropy modulation approach.
