“…There are several major technical challenges that impedes widespread application of CNTs in future electronics. Some of these challenges are more application specific, for instance, the controlled synthesis and placement of CNT is a main challenge in transistor applications, [11][12][13] while for bulk composite, the uniform dispersion is the main issue. On the other hand, poor interfacial interaction between metals and CNTs is a more universal problem and is detrimental to many applications.…”

“…Carbon nanotubes (CNTs), [ 1 ] especially single‐walled CNTs (SWCNTs), [ 2 ] have attracted great attentions since 1991 owing to their structure ( i.e ., chirality) dependent extraordinary properties. Research and development of CNT applications keep on expanding as well, covering energy harvesting, [ 3‐4 ] water treatment, [ 5 ] transparent conductive thin‐films, [ 6 ] flexible and printed electronics, [ 7‐10 ] ultrahigh conductive fibers, [ 11‐13 ] next generation electronics, [ 14‐20 ] photonics, [ 21‐26 ] biological imaging, [ 27‐28 ] and high‐efficiency photovoltaic process (Figure 1). [ 29‐30 ] Many of these applications are enabled by the unique properties of SWCNTs.…”

Carbon nanotubes (CNTs) present unique properties determined by their chiral structure. The main hurdle towards the wide applications is the difficulty to control the structure of CNTs and their hybrids that determines the properties. Precise synthesis with well-defined templates is a promising approach to control the identical structure of carbon nanomaterials. In this review, we summarize main achievements on controlled synthesis of CNTs and hybrids on two aspects: chirality-specific growth of CNTs from well-defined catalysts and nanocarbon templates, atomically precise synthesis of one-dimensional (1D) materials with the templates of CNTs. In the chirality-controlled growth part, we focus on the design of structural templates and growth mechanisms. In the synthesis of CNT hybrids part, we organize the existing strategies based on types of 1D hybrids templated by CNTs, including confined nanotubes, linear carbon chains, nanowires, quasi-1D van der-Waals materials. The main advantages, challenges, and perspectives in further development are discussed.Xusheng Yang (top left) received his B.S. degree at Lanzhou University in 2019 and now is a M.S. candidate under Prof.

“…Individual semiconducting single-walled carbon nanotubes (SWCNTs) have been selected as the channel materials to build field effect transistors (FETs) and microprocessors due to their extremely high carrier mobility [ 1 , 2 ]. The SWCNTs can be either metallic or semiconducting according to their chirality [ 3 ], and the contact resistance between metallic SWCNTs and metal electrodes is large; there will be a large Schottky barrier at the contact interface between semiconducting SWCNTs and metal electrodes [ 4 , 5 ].…”

Determining the metallicity and semiconductivity of a multi-walled carbon nanotube (MWCNT) bundle plays a particularly vital role in its interconnection with the metal electrode of an integrated circuit. In this paper, an effective method is proposed to determine the electrical transport properties of an MWCNT bundle using a current–voltage characteristic curve during its electrical breakdown. We established the reliable electrical nanoscale contact between the MWCNT bundle and metal electrode using a robotic manipulation system under scanning electron microscope (SEM) vacuum conditions. The experimental results show that the current–voltage curve appears as saw-tooth-like current changes including up and down steps, which signify the conductance and breakdown of carbon shells in the MWCNT bundle, respectively. Additionally, the power law nonlinear behavior of the current–voltage curve indicates that the MWCNT bundle is semiconducting. The molecular dynamics simulation explains that the electron transport between the inner carbon shells, between the outermost carbon shells and gold metal electrode and between the outermost carbons shells of two adjacent individual three-walled carbon nanotubes (TWCNTs) is through their radial deformation. Density functional theory (DFT) calculations elucidate the electron transport mechanism between the gold surface and double-wall carbon nanotube (DWCNT) and between the inner and outermost carbon shells of DWCNT using the charge density difference, electrostatic potential and partial density of states.
