Charge trapping (CT) and fixed charge (FC) are considered in the model of transient negative capacitance (TNC). The roles of CT and FC on subthreshold characteristics of ferroelectric FET (FeFET) are investigated by experiment and simulation. The simulation results show that both CT and FC can modulate the subthreshold characteristics of FeFET by shifting the operation point dynamically and statically, respectively. In addition, ferroelectric hysteresis can be reduced by the compensation due to CT and minor loop formation due to FC in a certain ${V}_{g}$ sweep range. As a result, sub-60 mV/decade subthreshold swing (SS) with nearly hysteresis-free operation observed in experiments can be qualitatively reproduced by our simulation framework of TNC if both CT and FC are well-considered.

电荷俘获和固定电荷对FeFET亚阈值特性的作用研究

在瞬态负电容(TNC)模型中考虑了电荷捕获(CT)和固定电荷(FC)。通过实验和仿真研究了CT和FC对铁电FET亚阈值特性的作用。仿真结果表明,CT和FC均可分别通过动态和静态移动工作点来调节FeFET的亚阈值特性。另外,在一定的条件下,可以通过CT补偿和FC引起的小环路形成来减少铁电磁滞。 $ {V} _ {g} $ 扫描范围。结果,如果我们充分考虑了CT和FC,可以通过我们的TNC仿真框架来定性地再现实验中观察到的接近60mV /十年的亚阈值摆幅(SS),几乎没有磁滞运行。
