Abstract
We propose a new method suited for the extraction of the threshold voltage in 2D Field-Effect-Transistors. It can be applied to various classes of devices where the mobility exhibits a power-law dependence on carrier concentration, μ ∝ nSα. The result doesn't depend on contact resistance. The method provides a physically sound value: VG-VT is proportional to the channel carrier density as checked with VG-dependent Hall measurements in companion gated Hall devices.
