Dual-channel P -type ternary DNTT–graphene barristor

P -type ternary switch devices are crucial elements for the practical implementation of complementary ternary circuits. This report demonstrates a p -type ternary device showing three distinct electrical output states with controllable threshold voltage values using a dual-channel dinaphtho[2,3- b :2′,3′- f ]thieno[3,2- b ]-thiophene–graphene barristor structure. To obtain transfer characteristics with distinctively separated ternary states, novel structures called contact-resistive and contact-doping layers were developed. The feasibility of a complementary standard ternary inverter design around 1 V was demonstrated using the experimentally calibrated ternary device model.
