“…TFTs are essential electronic components, for example, screen panels, Radio-frequency identification (RFID), Printed circuit board (PCB), electric sensors, and so on. Comparatively complex circuits based upon CNT-TFTs, like Ring oscillator [239], sensor system [240] and complementary metal oxide semiconductor (CMOS) type 4-bit complete adding machine [241], have been described at both stiff and stretchy supports. This progress displays the exceptional commitment of the CNT-TFTs upon coming macroelectronics.…”

Carbon nanotube (CNT)-doped transparent conductive films (TCFs) is an encouraging option toward generally utilized indium tin oxide-depended TCFs for prospective stretchable optoelectronic materials. Industrial specifications of TCFs involve not just with high electrical performance and transparency but also amidst environmental resistance and mechanical characteristic; those are usually excused within the research background. Though the optoelectronic properties of these sheets require to be developed to match the necessities of various strategies. While, the electrical stability of single-walled CNT TCFs is essentially circumscribed through the inherent resistivity of single SWCNTs and their coupling confrontation in systems. The main encouraging implementations, CNT-doped TCFs, is a substitute system during approaching electronics to succeed established TCFs, that utilize indium tin oxide. Here we review, a thorough summary of CNT-based TCFs including an overview, properties, history, synthesis protocol covering patterning of the films, properties and implementation. There is the attention given on the optoelectronic features of films and doping effect including applications for sophisticated purposes. Concluding notes are given to recommend a prospective investigation into this field towards real-world applicability. Graphic abstract This graphical abstract shows the overview of different properties (mechanical, electrical, sensitivity and transportation), synthesis protocols and designing (dry and wet protocol, designing by surface cohesive inkjet-printed and the support of polymers), doping effect (general doping, metal halides, conductive polymers and graphene for transparent electrodes) and implementations (sensing panels, organic light-emitting diodes devices, thin-film transistors and bio-organic interface) of carbon nanotubes transparent conductive films.

electronic, [3-4,4] and functional requirements. [5] Conventional silicon integrated circuit (IC) technology faces significant challenges in meeting these demands due to its limited mechanical flexibility, high temperature processing, and scaling limitations. Emerging alternative computing platforms based on other crystalline semiconductors suffer from similar limitations. Consequently, nextgeneration computing necessitates the exploration of radically different electronic materials. Single-walled carbon nanotubes (SWCNTs) are among the most promising and highly studied nanoelectronic materials. Due to their small size, [6,7] solutionprocessability, [8] chemical stability, [9] and chirality-dependent optoelectronic properties, [10] SWCNTs offer a number of unique advantages and are compatible with the complex requirements of future computing devices. Recent advances in chiral enrichment of polydisperse SWCNTs [8,10] have allowed their use as semiconducting channels in diverse settings including charge transport devices, [2] optical emitters and detectors, [11,12] and chemical sensors. [2,3,13,14] With this tunable functionality, a range of SWCNT-based computing applications have been realized, such as printed digital logic, [15] sub-10 nm complementary metal-oxide-semiconductor (CMOS) field-effect transistors (FETs), [16] neuromorphic devices, [17] single-photon emitters (SPE), [18] and enantiomer-recognition sensors. [14] Herein, we discuss recent advances in SWCNT-based computing technologies that process, manage, and communicate information, with an emphasis on the enabling role of chiral enrichment. Section 2.1 defines the different levels of chiral enrichment. Sections 2.2 and 2.3 describe direct growth methods and post-processing purification of SWCNTs for electronic-type and monochiral enrichment. Section 3 discusses applications of electronic-type-enriched SWCNTs such as wearables, highly scaled FETs, 3D logic-memory integration, and neuromorphic devices. Section 4 outlines applications of monochiral-enriched SWCNTs including monochiral FETs, optical emitters, photodetectors, and optoelectronic ICs. Section 5 considers recent progress toward enantiomerically pure SWCNTs. Finally, Section 6 presents an outlook for SWCNTs in next-generation computing applications including a delineation of remaining challenges and future opportunities. For the past half century, silicon has served as the primary material platform for integrated circuit technology. However, the recent proliferation of nontraditional electronics, such as wearables, embedded systems, and lowpower portable devices, has led to increasingly complex mechanical and electrical performance requirements. Among emerging electronic materials, single-walled carbon nanotubes (SWCNTs) are promising candidates for next-generation computing as a result of their superlative electrical, optical, and mechanical properties. Moreover, their chirality-dependent properties enable a wide range of emerging electronic applications including sub-10 nm complementary fie...

“…Especially for HF applications, building ICs is difficult as this requires competitive passive devices (i.e., the BEOL), the development of which is time consuming and costly. Thus, so far only ring oscillators [113], [114] or simple amplifiers have been built on-chip [12], [87], [89], [104], [115]- [121] while HF specific circuits such as amplifiers, a mixer and a VCO have been realized in discrete form [122]- [124]. For CVD processed FETs, metallic tubes have so far limited the circuit performance.…”

RF CNTFETs are one of the most promising devices for surpassing incumbent RF-CMOS technology in the near future. Experimental proof of concept that outperformed Si CMOS at the 130 nm technology has already been achieved with a vast potential for improvements. This review compiles and compares the different CNT integration technologies, the achieved RF results as well as demonstrated RF circuits. Moreover, it suggests approaches to enhance the RF performance of CNTFETs further to allow more profound CNTFET based systems e.g., on flexible substrates, highly dense 3D stacks, heterogeneously combined with incumbent technologies or an all-CNT system on a chip.
