“…In another study using a similar waveguide‐SWCNT integration scheme, few‐chirality SWCNTs were found to have diameter‐dependent photocurrent generation properties, such that large diameter SWCNTs only contribute to photocurrent generation when the waveguide is photoexcited 179.

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...

Single-walled carbon nanotubes (SWCNTs) exhibit outstanding properties that make them appealing in a wide range of applications. However, their properties are variable depending on the tube helicity (chirality), which has been a challenge for a long time and needs to be effectively controlled. In recent years, tremendous efforts have been made to control the electrical type/chirality of nanotubes through both direct controlled synthesis and postsynthesis separation methods. Driven by these breakthroughs, the applications of separated families of SWCNTs in various fields have emerged as a new topic of research. In this Review, an overview of recent advances in the use of highly purified and well-separated SWCNTs in a comprehensive range of applications is presented including photovoltaics, transistors, batteries, sensors, light emitters, biological/medical fields, and others. Finally, important future directions for the utilization of separated SWCNTs in these fields are provided.

“…Since their discovery in the early nineties, single wall carbon nanotubes (SWNTs) have attracted great attention due to their potential for nanoscale electronics, sensors, photodetectors, solar cells, LEDs, and, more recently, photonics . Carbon nanotubes are characterized by ballistic transport (at low bias and within hundreds of nm) and single wall carbon nanotube field effect transistors (SWNT‐FETs) can have extremely high I ON / I OFF ratios .…”

International audienceFunctional and easy-to-integrate nanodevices operating in the telecom wavelength ranges are highly desirable. Indeed, the pursuit for faster, cheaper, and smaller transceivers for datacom applications is fueling the interest in alternative materials to develop the next generation of photonic devices. In this context, single wall carbon nanotubes (SWNTs) have demonstrated outstanding electrical and optical properties that make them an ideal material for the realization of ultracompact optoelectronic devices. Still, the mixture in chirality of as-synthesized SWNTs and the necessity of precise positioning of SWNT-based devices hinder the development of practical devices. Here, the realization of operational devices obtained using liquid solution-based techniques is reported, which allow high-purity sorting and localized deposition of aligned semiconducting SWNTs (s-SWNTs). More specifically, devices are demonstrated by combining a polymer assisted extraction method, which enables a very effective selection of s-SWNTs with a diameter of about 1–1.2 nm, with dielectrophoresis, which localizes the deposition onto silicon wafers in aligned arrays in-between prepat-terned electrodes. Thus, long semiconducting nanotubes directly contact the electrodes and, when asymmetric contacts (i.e., source and drain made of different metals) are used, each device can operate both as photoemitter and as photodetector in the telecom band around 1.55 µm in air at room temperature
