Abstract
Antiferroelectric lanthanum-modified PbZrO3 thin films with La contents between 0 and 6 at.% have been deposited on Pt(111)/Ti/SiO2/Si substrate by sol-gel route. On the extent of La-modification, maximum polarization (Pmax) and recoverable energy density (W) have been enhanced followed by their subsequent reduction. A maximum Pmax (~0.54 C/m2 at ~60 MV/m) as well as a maximum W (~14.9 J/cc at ~60 MV/m) have been achieved on 5% La modification. Both Pmax and W have been found to be strongly dependent on La-induced crystallographic orientations.
