摘要 利用薄膜-衬底系统二参量模型,研究了单层钛酸钡(BaTiO3)压电纳米薄膜系统在轴向应力下发生的弯曲。分析讨论了BaTiO3纳米薄膜的极化强度、极化电荷量及压电电势分布。根据力学平衡法求解出弯曲BaTiO3薄膜压电势以及薄膜弯曲曲率半径和薄膜内应变。结果表明,本工作的理论模型计算的结果与Park等报道的实验及有限元模拟结果非常符合,给出了压电纳米薄膜发电机机理的简单模型和理论基础。

Abstract: Using the two-parameter model of the thin film-substrate system, the bending of the single-layer barium titanate (BaTiO3) nano-film system under axial stress was studied. The polarization intensity, polarization charge and piezoelectric potential distribution of BaTiO3 nano-film were analyzed and discussed. According to the mechanical balance method, the bending piezoelectric potential, the bending curvature radius and the strain of the BaTiO3 thin film were solved. The results showed that, the theoretical model and results of this paper are in good agreement with the experimental data and finite element simulation reported by Park et al, providing a simple theoretical model and basis for the mechanism of piezoelectric nanofilm generators.
