Summary: In this work, the polarity of carbon nanotube transistors was modulated using a chemical doping strategy. A p-type carbon nanotube transistor and an n-type carbon nanotube transistor were connected in series to construct an inverter and a Schmitt trigger. A ternary content-addressable memory cell was also built using two inverters. The results showed good performance and potential for future application in computing-in memory.

Summary: Ternary logic has been studied for decades and offers advantages in reducing interconnects and operation complexity, but existing ternary logic gates have too many transistors. The authors propose ultra-compact ternary logic gates based on the negative capacitance feature of ferroelectric materials and carbon nanotube field-effect transistors. Simulation results show correct and robust functionality, with significant improvements in transistor count, area, and energy-delay product compared to previous state-of-the-art ternary gates.

Summary: 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) formed by inkjet printing. The proposed device has a logic-in-memory characteristic that operates in either ternary or binary mode depending on the previous output voltage state. The device exhibits previous state dependent ternary/binary operations even after 4 days of exposure under ambient conditions and with 90 s of constant supply of bias stress.

Summary: By using Ar-ion etching to remove the top layer of the electrode surface before nanotube placement, the contact resistance at the nanotube-metal interface can be significantly reduced. This results in a tenfold decrease in the median ON-resistance of transistors and a more than two orders of magnitude decrease in the interquartile range of resistance values.
