论文摘要
本文介绍了金属 - 有线 - 胰蛋白酶 - 官方 - 苏制剂（MFIS）FET中多域的分析建模和动力学。多域（MD）的形成导致在通道中的传导带中振荡，并在铁电区的局部电场中周期性。 2-D本地电场对MD开关的影响是在模型中使用域墙速度概念捕获的。计算了氧化物厚度，铁电厚度和通道长度的最佳值，这对应于单域设备操作。偏离最佳设备参数会导致单域状态向铁电中的多域状态的过渡。这项工作可以用作设计MFIS-NCFET的指南，该指南提供了导致MFIS-NCFET中单域状态的设备参数。
Analytical modeling and dynamics of multidomain in metal-ferroelectric-insulator-semiconductor (MFIS)-FETs are presented in this paper. The formation of multi-domain (MD) leads to oscillations in the conduction band in the channel and periodicity in the local electric field in the ferroelectric region. The impact of 2-D local electric field on the MD switching is captured in the model using the domain wall velocity concept. The optimum values of oxide thickness, ferroelectric thickness and channel length are calculated which corresponds to mono-domain device operation. Deviation from the optimum device parameters causes the transition of mono-domain state to multi-domain state in the ferroelectric. This work can be used as a guideline for designing MFIS-NCFETs, which provides the device parameters that leads to monodomain state in the MFIS-NCFET.
