For 10 points, name this potential, the point at which diodes or transistors turn on and allows current to flow, which is often referred to as V sub t.
The Fermi potential relates this parameter to the doping level of the semiconductor. In modern device processes, it is typically adjusted to the desired value by performing a channel stop implant. Empirically, it can be determined by extrapolating the slope of an I-V curve from the linear region to the x-axis. In p-channel devices, it is typically positive, while in n-channel devices it is typically negative. This characteristic describes the point when a strong enough vertical electric field exists to create an inversion channel on top of a depletion region in a MOSFET.
