    A flexible and wearable terahertz scanner based on carbon nanotubes is demonstrated at room temperature over a frequency range 0.14 THz to 39 THz. The terahertz photothermoelectricity is enhanced by using different electrode materials.

    Researchers have observed light propagation in which photons glide smoothly along a one-dimensional chain of electrons known as a Luttinger liquid — a many-body interacting quantum system held within a single-walled carbon nanotube.

    By integrating a photoacoustic transmitter based on a carbon nanotube nanocomposite and an optical microring resonator as an ultrasonic sensor, a low-noise terahertz pulse detection system is demonstrated at room temperature. The response time and the noise-equivalent detectability energy are on the order of 0.1 µs and 220 pJ, respectively.

    A photodiode-based logic device employing scalable heterojunctions of carbon nanotubes and silicon whose output currents can be manipulated by both optical and electrical inputs is developed. Bidirectional phototransistors and novel clock-triggerable logic elements, such as a mixed optoelectronic AND gate, a 2-Bit optoelectronic ADDER/OR gate and a 4-Bit optoelectronic D/A converter, are also demonstrated.

    Little is known about triplet excitons in semiconducting single-walled nanotubes, despite their importance in various applications. The pump–probe and spin-sensitive photoluminescence of such nanotubes is studied, and the quantum yield of triplet formation, triplet lifetime and triplet exciton size are found to be 5 ± 2%, 30 ± 10 µs and 0.65 nm, respectively.

    Clear evidence is presented for the origins of photocurrent generation in metallic and semiconducting carbon nanotubes — photocurrent is found to be mainly generated by photothermal and photovoltaic effects in metallic and semiconducting carbon nanotubes, respectively. This finding will enable the engineering of highly efficient carbon-based photodetectors and energy-harvesting devices.

    The use of Raman spectroscopy for high-resolution optical imaging is severely limited by the inherent weakness of the Raman effect. Now, a giant resonant Raman effect is demonstrated from J-aggregated dye molecules encapsulated in single-walled carbon nanotubes, and it is used to realize multispectral Raman imaging.

    Nanotubes and graphene have emerged as promising materials for use in ultrafast fibre lasers. Their unique electrical and optical properties enable them to be used as saturable absorbers that have fast responses and broadband operation and that can be easily integrated in fibre lasers.

    Artificially reducing the effective dimensionality of carbon nanotubes from one to zero dimensions increases the luminescence quantum yield of excitons confined in zero-dimensional-like states to ∼18%, which is over one order of magnitude larger than that of intrinsic one-dimensional excitons (∼1%). This finding will help realize future nanoscale photonic devices.

    A simple two-terminal device containing a semiconducting single-walled-nanotube thin-film is reported that generates an extremely high density of holes when it comes in contact with an ionic liquid, inducing strong electromodulation of the interband and excitonic transitions as a result of the position-dependent shift of the single-walled-nanotube Fermi level.

    Photovoltages generated from semiconducting single-walled carbon nanotubes are often too small for most practical solar-energy-harvesting applications. Here, researchers demonstrate that virtual contacts can be used to multiply photovoltages from around 0.2 V to 1.0 V.
