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 low‐power 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 field‐effect transistors, optoelectronic integrated circuits, and enantiomer‐recognition sensors. Here, recent progress in SWCNT‐based computing devices is reviewed, with an emphasis on the relationship between chirality enrichment and electronic functionality. In particular, after highlighting chirality‐dependent SWCNT properties and chirality enrichment methods, the range of computing applications that have been demonstrated using chirality‐enriched SWCNTs are summarized. By identifying remaining challenges and opportunities, this work provides a roadmap for next‐generation SWCNT‐based computing.
