论文摘要
探索了与迁移率广泛分布的电子和离子电荷表面系统相互作用的单轴铁电纳米颗粒的极性状态，这与溶液或环境条件下的纳米颗粒的实验案例相对应。铁电偶极子与表面电荷之间具有缓慢弛豫动力学的表面电荷之间的非线性相互作用，导致出现了广泛的类似降压型，抗抗抗抗抗抗抗抗逆抗的离子和铁电源的铁状铁状态。这些状态之间的交叉不仅可以通过表面电荷的静态特征来控制，而且可以通过其在应用场中的松弛动力来控制。获得的结果不仅是对铁电纳米颗粒在纳米电子和光电子学中的高级应用，还提供了实验验证的策略。
The polar states of uniaxial ferroelectric nanoparticles interacting with a surface system of electronic and ionic charges with a broad distribution of mobilities is explored, which corresponds to the experimental case of nanoparticles in solution or ambient conditions. The nonlinear interactions between the ferroelectric dipoles and surface charges with slow relaxation dynamics in an external field lead to the emergence of a broad range of paraelectric-like, antiferroelectric-like ionic, and ferroelectric-like ferroionic states. The crossover between these states can be controlled not only by the static characteristics of the surface charges, but also by their relaxation dynamics in the applied field. Obtained results are not only promising for advanced applications of ferroelectric nanoparticles in nanoelectronics and optoelectronics, they also offer strategies for experimental verification.
