A GHeT includes a bottom gate formed on a substrate; a first dielectric layer (DL) formed on the bottom gate; a monolayer film formed of an atomically thin material on the first DL; a bottom contact (BC) formed on part of the monolayer film; a second DL formed on the BC; a top contact (TC) formed on the second DL on top of the BC; a network of CNTs formed on the TC and the monolayer film, to define an overlap region with the monolayer film; a third DL formed on the CNT network, the monolayer film and the TC; and a top gate formed on the third DL and overlapping with the overlap region. Such GHeT design allows gate tunability of Gaussian peak position, height and width that define Gaussian transfer characteristic, thereby enabling simplified circuit architectures for various spiking neuron functions for emerging neuromorphic applications.
