THRESHOLD VOLTAGE for MOSFET

Threshold Voltage commonly abbreviated as Vth or VGS (th) the minimum gate-to-source voltage differential that is needed to create a conducting path between the source and drain terminals.

Simulation result for formation of inversion channel (electron density) and attainment of threshold voltage (IV) in a nanowire MOSFET. Note that the threshold voltage for this device lies around 0.45 V.
