“…Both quantities are determined through combined STM and STS measurements. The first reported STM experiments on multi-walled carbon nanotubes date back almost a decade (54,55). At that time, Ge & Sattler (56) recorded an STM image of a multi-walled nanotube that displayed an atomically resolved pattern affected by the two outermost layers of the tubes.…”

We review the recent progress in our understanding of the mechanical and electrical properties of carbon nanotubes, emphasizing the theoretical aspects. Nanotubes are the strongest materials known, but the ultimate limits of their strength have yet to be reached experimentally. Modeling of nanotube-reinforced composites indicates that the addition of small numbers of nanotubes may lead to a dramatic increase in the modulus, with only minimal crosslinking. Deformations in nanotube structures lead to novel structural transformations, some of which have clear electrical signatures that can be utilized in nanoscale sensors and devices. Chemical reactivity of nanotube walls is facilitated by strain, which can be used in processing and functionalization. Scanning tunneling microscopy and spectroscopy have provided a wealth of information about the structure and electronic properties of nanotubes, especially when coupled with appropriate theoretical models. Nanotubes are exceptional ballistic conductors, which can be used in a variety of nanodevices that can operate at room temperature. The quantum transport through nanotube structures is reviewed at some depth, and the critical roles played by band structure, one-dimensional confinement, and coupling to nanoscale contacts are emphasized. Because disorder or point defect-induced scattering is effectively averaged over the circumference of the nanotube, electrons can propagate ballistically over hundreds of nanometers. However, severe deformations or highly resistive contacts isolate nanotube segments and lead to the formation of quantum dots, which exhibit Coulomb blockade effects, even at room temperature. Metal-nanotube and nanotube-nanotube contacts range from highly transmissive to very resistive, depending on the symmetry of two structures, the charge transfer, and the detailed rehybridization of the wave functions. The progress in terms of nanotube applications has been extraordinarily rapid, as evidenced by the development of several nanotube-based prototypical devices, including memory and logic circuits, chemical sensors, electron emitters and electromechanical actuators.

“…Moiré patterns in one-dimensional (1D) systems have received less attention than their two-dimensional counterparts, although once they are formed, they will be extremely stable and the 1D confinement introduces an additional degree of freedom for manipulating states. − Double-walled carbon nanotubes (DWCNTs) have distinct moiré patterns that arise from the two concentrically aligned single-walled carbon nanotubes with different twists along their axis . Depending on the chirality of the two tubes, the band gap shrinks due to the moiré interaction , or insulating flat bands are expected, very similar to those found in bilayer graphene .…”

Moiré patterns are additional, long-range periodicities in twisted crystalline bilayers. They are known to fundamentally change the electronic states of the layers, but similar effects on their mechanical and vibrational properties have not been discussed so far. Here we show that the Moiré potential shifts the radial breathing mode in double walled carbon nanotubes (DWCNTs). It is expected that the frequency change is proportional to the shift in optical transition energies, which are induced by the Moiré patterns. To verify our model we performed resonant Raman scattering on the purified and sorted semiconducting DWCNTs. We find that the radial breathing mode in the Raman spectra of DWCNTs is up to 14 cm -1 higher in energy and their optical transitions energies up to 200 meV lower in energy than in the corresponding single-walled tubes. The shift follows the expected linear correlation with a slope -88 eV/cm -1 . We show how to identify the strong coupling condition in DWCNTs from their phonon frequencies and construct a Kataura plot to aid their future experimental assignment.
