Web1 Aug 2024 · In this context, the subthreshold swing, SS = dV g /dLn (I d ), V g being the gate voltage, is a key parameter measuring the turn-on capability of the MOSFET. Recently, it has been shown that the saturation of the subthreshold swing at cryogenic temperatures could originate from an exponential tail of states at the 2D subband edge [10], [11]. Web15 May 2024 · Abstract: Al 2 O 3-passivated Schottky-gate AlGaN/GaN high electron mobility transistors (HEMTs) with improved subthreshold swing (SS) and drain current ON/OFF ratio by postmetallization annealing (PMA) at 500 °C in N 2 ambient are reported. With the PMA, the gate leakage current in the reverse biased region and the OFF-state drain current are … Web1 Mar 2001 · The subthreshold swing, S, is defined as the change in gate bias required to change the subthreshold drain current by one decade, and is given by: (1) S≡ ∂ V g ∂ log I D, where Vg is the gate voltage and ID the drain current. trilyn harper

The subthreshold swing is measured at one drain current corresponding to a certain surface potential, given by eq. (1) at zero substrate bias. When substrate biases are applied to … 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…
