“…Additionally, this fabrication scheme has been utilized to fabricate CMOS inverters with a pitch size as small as 240 nm. [16] While these advances highlight the potential of SWCNT FETs in aggressively scaled digital technologies, a deeper understanding of how channel length scaling affects other performance metrics (e.g., early device degradation) [121] is needed.…”

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...

“…Stability and reliability are important concerns to CNT electronics. Few works focused on the stability of CNTFETs [84,85]. CNTFETs, especially the N-type CNTFETs implemented by low work function metal contact, would be sensitive to air, and/or gradually degrade or even fail when exposed to the air without a package.…”

“…CNTFETs, especially the N-type CNTFETs implemented by low work function metal contact, would be sensitive to air, and/or gradually degrade or even fail when exposed to the air without a package. Although researchers have found that the stability of CNTFETs can be improved through passivation [84,85], some factors, especially including polymer residues in the most mature solution-derived CNTs and interface trapping states, will induce instability during the enduring operation. Additionally, fabricating CNT CMOS FETs with standard industry processes, which are compatible with conventional CMOS processes, is a significant necessity for developing CNT-based integrated circuits.…”

Over the last sixty years, the scaling of silicon-based complementary metal-oxide-semiconductor (CMOS) field-effect transistors (FETs) have promoted the rapid development of microelectronic technology. However, the development of Si CMOS technology is currently subject to serious challenges from various aspects such as physics limit, cost, and power consumption, and is becoming increasingly difficult. Material innovation is exerting an ever-greater role in the integrated circuit design. By looking for thinner semiconductor materials with higher mobility as the active layer to construct smaller and higher-performance transistors, it is possible to further stimulate transistors and integrated circuits on performance, density, power dissipation, and functions. In 1991, Iijima discovered carbon nanotubes (CNTs). Due to its excellent electrical properties and intrinsic nano-scale size, CNT has been considered by academia and industry to have great potential to replace silicon materials in the future for the extremely scaled technology nodes or novel electronic applications. This paper reviews the latest advancements in CNT-based electronics research. Finally, the challenges and pathways for nanotube transistors to transition into commercial applications are discussed.

“…Their fascinating structures have attracted attention of numerous researchers. CNTs are seamless nanoscale tubes made of a single or multilayer graphite coiled at a certain helical angle around a central axis (De Volder et al, 2013 ; Noyce et al, 2019 ). Because of its wide range of thermal, structural, and electronic properties, they have been applied to catalyst and capacitor material support (Gong et al, 2013 ; Yang et al, 2017 ).…”

Metabolic diseases have become common diseases with the improvement of living standards because of changed dietary habits and living habits, which seriously affect health. Currently, related biomarkers have been widely used as important indicators for clinical diagnosis, treatment, and prognosis of metabolic diseases. Among all detection methods for biomarkers of metabolic diseases, electrochemical sensor technology has the advantages of simplicity, real-time analysis, and low cost. Carbon nanomaterials were preeminent materials for fabricating electrochemical sensors in order to enhance the performance. In this paper, we summarize the research progress in the past 3 years of electrochemical sensors based on carbon nanomaterials in detecting markers of metabolic diseases, which include carbon nanotubes, graphene, carbon quantum dots, fullerene, and carbon nitride. Additionally, we discuss the future prospects for this field.
