A CMOS-like inverter was integrated by using ambipolar carbon nanotube (CNT) transistors without doping. The ambipolar CNT transistors automatically configure themselves to play a role as an n-type or p-type transistor in a logic circuit depending on the supply voltage (V(DD)) and ground. A NOR (NAND) gate is adaptively converted to a NAND (NOR) gate. This adaptiveness of logic gates exhibiting two logic gate functions in a single logic circuit offers a new opportunity for designing logic…

CMOS-based carbon nanotube pass-transistor logic integrated circuits
TLDR
It is demonstrated that a significant reduction in the use of field-effect transistors can be achieved by constructing carbon nanotube-based integrated circuits based on a pass-transistor logic configuration, rather than a complementary metal-oxide semiconductor configuration.
Scalable complementary logic gates with chemically doped semiconducting carbon nanotube transistors.
TLDR
A scalable and cost-effective fabrication of complementary logic gates by precisely positioning an air-stable n-type dopant, viologen, by inkjet printing on a separated semiconducting CNTs network is reported.
Organic Ambipolar Transistors and Circuits
Ambipolar charge transport of a variety of small molecules and polymers has initiated research on ambipolar transistors and circuits. Such electronic devices can be fabricated at low temperatures on…
Carbon nanotube field-effect transistors for use as pass transistors in integrated logic gates and full subtractor circuits.
TLDR
The use of carbon nanotube (CNT)-based field-effect transistors (FETs) as pass transistors is investigated and a one-bit full subtractor is realized on individual CNTs for the first time using the PTL style with only three pairs of n- and p- FETs.
Complementary-like graphene logic gates controlled by electrostatic doping.
TLDR
This method provides a possible route for logic circuits from ambipolar graphene and, in principle, can be also extended to other ambipolar semiconductors, such as organic compounds and carbon nanotube thin films.

Majority carrier type conversion with floating gates in carbon nanotube transistors.
TLDR
It is demonstrated here that reversible conversion from p- to n-type can be robustly realized in CNT eld-effect transistors by changing the polarity of trapped charges.
Highly stable carbon nanotube top-gate transistors with tunable threshold voltage.
TLDR
Continuous tuning of the threshold voltages of both unipolar and ambipolar SWNT thin-film transistors (TFTs) is demonstrated for the first time.
Enhancement of ambipolar characteristics in single-walled carbon nanotubes using C60 and fabrication of logic gates
We demonstrate a technique to convert p-type single-walled carbon nanotube (SWNT) network transistor into ambipolar transistor by thermally evaporating C60 on top. The addition of C60 was observed to…
