“…Albeit the great difficulties, this approach is the most rewarding one in terms of crossinformation gained from the use of multitude of techniques and is therefore an important vector in studying the structurefunction relationship of nanomaterials in general and nanotubes, in particular. [127][128][129][130][131][132] Equally important is the fact that, recent advances in ab-initio calculations permits quantitative comparison between theory and experimental results of individual nanotubes, which was not there two decades ago.…”

“…In our case we used ethanol and water vapor during the growth stage together with the sufficient amount of the main precursor – acetylene. The long individual semiconducting nanotubes with the strong optical signals can serve as the reference model for the testing of the excitonic properties of hybrid materials created by filling channels of SWCNTs …”

The monodispersed long single‐wall carbon nanotubes (SWCNTs) with controlled morphology are promising in various research fields and many applications, such as optoelectronics, nanoelectronics and recently upon utilizing them as nanoreactors. In this work the long aligned semiconducting single‐walled carbon nanotubes as well as the extended semiconducting nanotube networks are synthesized via a vapor‐phase epitaxial (VPE) cloning growth method. The semiconducting nanotubes are grown on ST‐cut quartz substrates using acetylene and ethanol as a precursors from the seeds of sorted SWCNTs. According to the conducted study the length of the grown nanotubes can reach up to 70 μm. The extensive optical study confirms the preservation of SWCNTs chirality during re‐growth from nanotube seeds and the high quality of the obtained long semiconducting nanotubes. Polarization dependent Raman demonstrates the high alignment degree of the re‐grown SWCNTs. In dense growth regime SWCNTs demonstrate strong Raman response due to the smaller amount of defects. Such networks of SWCNTs can be a good candidate for optoelectronic applications.

“…A well-known consequence of such rapid nonradiative decay is the photoluminescence quenching of the inner layers of DWCNTs, which leads to at least four orders of magnitude decrease of the PL intensity relative to freestanding SWCNTs. [24] In principle, this quenching can be manipulated through 1D heterostructure engineering, e.g., using insulating outer boron nitride layers instead of a CNT layer, as will be discussed further in other sections of this review.…”

“…It led to the most significant discoveries of the effect of vdW coupling on DWCNT properties. [19][20][21][22][23][24][25] This vdW coupling can affect the heterostructure properties both from the "inside" and "outside." For instance, throughout the years, the hollow inner space of SWCNTs has generated much creativity in designing new heterostructures by encapsulation of various materials.…”

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.
