Introduction to PTM and HyperFET. (a) PTM structure. Here, Pd/Au is the metal electrode, and the green zone is the channel. (b) HyperFET structure, which can be achieved by integrating PTM in the source terminal of a MOSFET (c) Current vs. voltage characteristics of a PTM. (d) |ID| vs. |VGS| of the HyperFET. Here, ID is the drain current, and VGS is the gate to source voltage of the HyperFET. (e) A P-type HyperFET circuit symbol.
