摘要

Environmentally benign Bi_(3.25)La_(0.75)Ti_3O_(12) (BLTO) thin film capacitors were prepared by a cost effective chemical solution deposition method for high energy density storage device applications. Low annealing temperature annealed BLTO thin films showed very slim hysteresis loops with high maximum and small remnant polarization values. Increasing the applied electric field to 2040 kV/cm, the optimized BLTO thin films show a high recoverable energy density of 44.7 J/cm~3 and an energy efficiency of 78.4% at room temperature. Additionally, the BLTO thin film capacitors exhibited excellent fatigue endurance after 4 x 10~8 cycles and a good thermal stability up to 140 ℃, proving their strong potential for high energy density storage and conversion applications.
