“…bundles of SWCNTs sheathed with BNNTs and MoS 2 NTs (C@ BN@MoS 2 NT) (Figure 11e) has been investigated by ultrafast pump-probe spectroscopy across the visible and terahertz frequency ranges. [188] The transient absorbance in the UV and visible range at different pump-probe delay times after femtosecond pulsed excitation was traced to identify whether excitons in the MoS 2 NTs are the major photoproduct upon light absorption by MoS 2 layers of the heterostructure. Figure 2f presents the fitted transient absorbance in the range near the A and B excitons from C@BN@MoS 2 NT heteronanotubes.…”

1D van der Waals heterostructures based on carbon nanotube templates are raising a lot of excitement due to the possibility of creating new optical and electronic properties, by either confining molecules inside their hollow core or by adding layers on the outside of the nanotube. In contrast to their 2D analogs, where the number of layers, atomic type and relative orientation of the constituting layers are the main parameters defining physical properties, 1D heterostructures provide an additional degree of freedom, i.e., their specific diameter and chiral structure, for engineering their characteristics. The current state-of-the-art in synthesizing 1D heterostructures are discussed here, in particular focusing on their resulting optical properties, and details the vast parameter space that can be used to design heterostructures with custombuilt properties that can be integrated into a large variety of applications. First, the effects of van der Waals coupling on the properties of the simplest and best-studied 1D heterostructure, namely a double-walled carbon nanotube, are described, and then heterostructures built from the inside and the outside are considered, which all use a nanotube as a template, and, finally, an outlook is provided for the future of this research field.

The experimental synthesis of 1D van der Waals heterostructures, a class of materials in which different crystallized nanotubes are coaxially nested, was recently demonstrated. In this perspective, the current challenges in the chemical vapor deposition synthesis of this new structure are outlined, and the visions on its potential applications are presented. A particular emphasis is given to electronic devices that are built after modulating different shell–shell combinations in these heteronanotubes.

“…The obtained 1D vdW heterostructures were found to exhibit unique optoelectronic properties. 7 Due to their superior thermal conductivity and outstanding mechanical stability, these 1D vdW heterostructures can serve as promising thermal interface materials in solving the problem of heat dissipation in modern electronic devices. 8 However, the thermal property of 1D heterostructures is still almost unexplored despite that the thermal transport behaviors of their pristine counterparts such as CNT, 9,10 BNNT, 11 and MSNT, 12,13 have been well investigated.…”

In this paper, we conduct a comprehensive investigation on the thermal transport in one-dimensional (1D) van der Waals (vdW) heterostructures by using non-equilibrium molecular dynamics simulations. It is found that the boron nitride nanotube (BNNT) coating can increase the thermal conductance of inner carbon nanotube (CNT) base by 36%, while the molybdenum disulfide nanotube (<a>MSNT</a>) coating can reduce the thermal conductance by 47%. The different effects of BNNT and MSNT coatings on the thermal transport behaviors of 1D vdW heterostructures are explained by the competition mechanism between improved heat flux and increased temperature gradient in 1D vdW heterostructures. By taking CNT@BNNT@MSNT as an example, thermal transport in 1D vdW heterostructures containing three layers is also investigated. It is found that the coaxial BNNT-MSNT coating can significantly reduce the thermal conductance of inner CNT base by 61%, which is even larger than that of an individual MSNT coating. This unexpected reduction in thermal conductance of CNT@BNNT@MSNT can be explained by the suppression of heat flux arising from the possible compression effect, since BNNT-MSNT coating in CNT@BNNT@MSNT can more significantly suppress the vibration of inner CNT when compared to the individual MSNT coating in CNT@MSNT. In addition to the in-plane thermal transport, the interfacial thermal conductance between inner and outer nanotubes in 1D vdW heterostructures is also examined to provide a quantitative understanding of the thermal transport behaviors of1D vdW heterostructures. This work is expected to provide molecular insights into tailoring the heat transport in carbon base 1D vdW heterostructures and thus facilitate their broader applications as thermal interface materials.
