平带电压(Flat band voltage)就是在MOS系统中,使半导体表面能带拉平(呈平带状态)所需要外加的电压。 平带状态一般是指理想MOS系统中各个区域的能带都是拉平的一种状态。 对于实际的MOS系统,由于金属-半导体功函数差φms和Si-SiO2系统中电荷Qf 的影响, 在外加栅极电压为0 时,半导体表面的能带即发生了弯曲,从而这时...

This article reports and models the impact of fixed oxide charges distributed spatially in the gate oxide of a metal-oxide-semiconductor (MOS) structure on its flatband voltage. In general analyses, the location of fixed oxide charges is effectively considered at the oxide-semiconductor interface ...
所以叫MOS,也叫MIS(Metal-Insulator-Semiconductor)。 介绍这样的MOS-C的结构之前,先介绍一个概念平带电压(Vfb, Flat-Band Voltage)。当栅极无偏压时候,理想情况下金属功函数qΦm与半导体功函数qΦs的能量差应该为零,也就是金属和半导体的功函数差qΦms等于零。也就是说零偏压下,能带是平的所以叫做平带。而在...

The flat-band voltage VFB is an important parameter of any MOS structure since its value influences the threshold voltage VT , which decides for example about power consumption of MOS transistors. One of the methods to measure the VFB value is the electric method of C(V) characteristic. This...
Capacitance and Voltage: The capacitance of an MOS capacitor changes depending on the voltage applied to the gate, affecting how charges are distributed within the device. Flat Band Voltage: This critical voltage level signifies no net charge across the capacitor, establishing a baseline for measurin...
