Abstract

Antiferroelectric lanthanum-modified $PbZrO_3$ thin films with La contents between 0 and 6 at. % have been deposited on Pt(111) $/Ti/SiO_2/Si$ substrate by sol-gel route. On the extent of La-modification, maximum polarization $(P_{max})$ and recoverable energy density (W) have been enhanced followed by their subsequent reduction. A maximum $P_{max}$ $(\sim 0.54 C/m^2$ at $\sim 60 MV/m$ as well as a maximum W $(\sim 14.9 J /cc$ at $\sim 60 MV/m)$ have been achieved on 5% La modification. Both $P_{max}$ and W have been found to be strongly dependent on La-induced crystallographic orientations.
