ABSTRACT
Anti-ambipolar switch (AAS) devices at a narrow bias region are necessary to solve the intrinsic leakage current problem of ternary logic circuits. In this study, an AAS device with a very high peak-to-valley ratio (â¼106) and adjustable operating range characteristics was successfully demonstrated using a ZnO and dinaphtho[2,3-b2',3'-f]thieno[3,2-b]thiophene heterojunction structure. The entire device integration was completed at a low thermal budget of less than 200 °C, which makes this AAS device compatible with monolithic 3D integration. A 1-trit ternary full adder designed with this AAS device exhibits excellent power-delay product performance (â¼122 aJ) with extremely low power (â¼0.15 µW, 7 times lower than the reference circuit) and lower device count than those of other ternary device candidates.
