Carbon nanotubes and fullerenes are allotropes of carbon characterized by a hollow structure and extraordinary thermal, electrical and mechanical properties. Spherical fullerenes are also called buckyballs, whereas cylindrical ones are known as nanotubes. The walls of these structures consist of a single layer of carbon atoms (graphene).
A single-walled carbon nanotube spring stores three times more mechanical energy than a lithium-ion battery, while offering wide temperature stability and posing no explosion risk.
Interlayer excitons in 2D homo- and heterostructures have been intensively investigated due to their emerging optical properties. Here, the authors report the observation of interface excitons in 1D/2D carbon nanotube/WSe2 heterostructures, showing evidence of photon antibunching at room temperature.
Metal-organic frameworks are versatile materials but typically suffer from poor electrical conductivity. Here, a patterning technique allows controlled metal-organic framework growth on predefined areas of functionalized carbon nanotube for increased conductivity.
A 3D stackable computing-in-memory array that is based on resistive random-access memory could accelerate the implementation of machine learning algorithms.
Carbon nanotube transistors with high performance and integration density can be created using a full-contact structure to scale the nanotube–electrode contact length.
Carbon nanotube field-effect transistors that are fabricated using aligned nanotube arrays exhibit an identical sequence of random ternary bits, which can be separated and used to generate security keys for encrypted communications.
