英文摘要	In this work, Pb1-3x/2LaxZrO3 (x = 0-0.12) (PLZ-x) antiferroelectric thin films were fabricated on Pt(111)/TiO2/SiO2/Si substrates using chemical solution method. Smaller cations (La3+) and vacancies were introduced into A-sites of perovskite structure to construct chemical pressure. According to phenomenological theory, chemical pressure can increase the energy barrier between antiferroelectric (AFE) and ferroelectric (FE) phase, and enhance antiferroelectricity of the system. As a result, a large energy storage density (W-re) of 23.1 J cm(-3) and high efficiency (eta) of 73% were obtained in PLZ-0.10 films, while PLZ-0 films displayed lower W-re (15.1 J cm(-3)) and eta (56%). More importantly, PLZ-0.10 films exhibited an excellent cycling stability with a variation of (similar to)2% after 1 x 10(8) cycles. The results demonstrate that heavily La-doped PbZrO3 films with high energy storage density, high efficiency and excellent cycling stability can be considered as potential candidates for energy storage applications.
