The electrical conductivity of metallic carbon nanotubes (CNTs) quickly saturates with respect to bias voltage due to scattering from a large population of optical phonons. The decay of these dominant scatterers in pristine CNTs is too slow to offset an increased generation rate at high voltage bias. We demonstrate from first principles that encapsulation of one-dimensional atomic chains within a single-walled CNT can enhance the decay of “hot” phonons by providing additional channels for…

Zigzag HgTe Nanowires Modify the Electron–Phonon Interaction in Chirality-Refined Single-Walled Carbon Nanotubes
Atomically thin nanowires (NWs) can be synthesized inside single-walled carbon nanotubes (SWCNTs) and feature unique crystal structures. Here we show that HgTe nanowires formed inside small-diameter
Stabilities and electronic properties of nanowires made of single atomic sulfur chains encapsulated in zigzag carbon nanotubes.
Theoretical investigations are carried out on the recently synthesized one-dimensional nanowires made of atomic sulfur chains encapsulated in carbon nanotubes, which confirm that the sulfur chains can improve the electronic transport of CNTs.
Structural and electronic transport properties of a SiC chain encapsulated inside a SiC nanotube: first-principles study.
A completely new hybrid structure with encapsulation of a linear SiC chain inside a SiCNT is designed, using first-principles calculation and the non-equilibrium Green's function formalism to systematically investigate the structural stability and electronic properties, particularly the quantum transport properties.
Electronic Structure Control of Sub-nanometer 1D SnTe via Nanostructuring within Single-Walled Carbon Nanotubes.
This paper exploits the capillarity of single-walled carbon nanotubes (SWCNTs) for the synthesis of the smallest possible SnTe nanowires with cross sections as thin as a single atom column, demonstrating that by choosing the appropriate diameter of a template SWCNT, one can manipulate the structure of the quasi-one-dimensional SnTe to design electronic behavior.
Single-Atom Scale Structural Selectivity in Te Nanowires Encapsulated Inside Ultranarrow, Single-Walled Carbon Nanotubes.
The ability to control functional properties of these ENs with confinement has numerous applications in future device technologies, and it is anticipated that this study will set the basic paradigm to be adopted in the characterization and understanding of such systems.

One-Dimensional Nanocomposites Based on Polypyrrole-Carbon Nanotubes and Their Thermoelectric Performance
The formed 1D nanocomposite samples showed that this MWCNTs were successfully coated by thick and thin layers of PPy, and these results might be useful for developing future TE materials and devices.
First-principles structure prediction of extreme nanowires
Low-dimensional systems are an important and intensely studied area of condensed matter physics. When a material is forced to adopt a low-dimensional structure, its behaviour is often dramatically
