论文摘要
大量的实验研究表明，由一对电极夹住的介电薄膜制成的两端电阻开关装置表现出可逆的多状态开关行为。但是，需要进一步追求对其电气特性的物理和化学起源的一致理解，以改善和自定义性能。在本文中，相位场方法用于研究导电通道的形成和an灭，导致可逆性的电阻开关行为通常可能发生在任何介电薄膜中。我们的重点是在空间变化的电场和温度的影响下由电荷制成的域的动态演变，从而导致电导的明显变化。
A large number of experimental studies suggest two-terminal resistive switching devices made of a dielectric thin film sandwiched by a pair of electrodes exhibit reversible multi-state switching behaviors; however coherent understanding of physical and chemical origins of their electrical properties needs to be further pursued to improve and customize the performance. In this paper, phase-field methodology is used to study the formation and annihilation of conductive channels resulting in reversible resistive switching behaviors that can generally occur in any dielectric thin films. Our focus is on the dynamical evolution of domains made of electrical charges under the influence of spatially varying electric field and temperature resulting in distinctive changes in electrical conductance.
