WebUsing our positive stress voltage data, we calculated the sub-threshold slope variations and extracted the interface trap density (Dit). Surprisingly, we found that the subthreshold slope... The subthreshold slope is a feature of a MOSFET's current–voltage characteristic. In the subthreshold region, the drain current behaviour – though being controlled by the gate terminal – is similar to the exponentially decreasing current of a forward biased diode. Therefore a plot of drain current versus gate voltage with drain, source, and bulk voltages fixed will exhibit approximately log linear behaviour in this MOSFET operating regime. Its slope is the subthreshol…
