Pre-State-Dependent Ternary/Binary Logic Operation Obtained by Inkjet Printed Indium Oxide and Single-Walled Carbon Nanotube/Indium Oxide Heterojunction-Based Transistors

Abstract

This work proposes a pre-state-dependent ternary and binary logic inverter using a single-walled carbon nanotube (SWCNT)/indium oxide (InO) heterojunction field-effect transistor (H-FET) which is reliably formed by an inkjet printing method. The proposed device exhibits a logic-in-memory characteristic that operates in either ternary or binary mode depending on the previous output voltage state. Such previous state dependent ternary/binary operations are observed even after 4 days of exposure under ambient conditions and with 90 s of constant supply of bias stress.
