Abstract
By expressing more than two logic states within given operating voltages without device scaling, multi-valued logic (MVL) circuits perform the same functions much more efficiently with less number of devices compared to binary logic circuits. Such MVL circuits can be often implemented by employing negative transconductance (NTC) devices whose channels are composed of van der Waals (vdW) pn heterojunctions of dissimilar semiconductors. In this work, we will demonstrate NTC devices and ternary inverter circuits using single semiconducting material. The pn homojunction-based devices show anti-ambipolar behavior with NTC characteristics. The resultant ternary inverters with three distinct logic states are successfully demonstrated.
