| Abstract Scope |
Semiconducting carbon nanotubes and graphene nanoribbons are poised to outperform Si and GaAs in future logic and wireless communications technologies. They can carry more current and switch on/off with less voltage, allowing for significantly faster microelectronics that use less power. However, substantial materials and nanomanufacturing challenges stand in the way. Specifically, new methods need to be developed for these nanomaterials’ synthesis, assembly, and organization. This presentation will highlight solutions to these challenges in two areas: (1) the large-area self-assembly of sorted semiconducting carbon nanotubes into dense arrays of aligned nanotubes using interfacial and confinement assembly, including integration into high-performance transistors [Science Advances (2021); Nanoscale Advances (2021); JAP (2022); Submitted (2023)] and (ii) the bottom-up synthesis of semiconducting nanoribbons as narrow as 2 nm with faceted armchair edges via CVD through control over the anisotropy of synthesis [Nano Letters (2018); ACS Nano (2021); Nature Communications (2022); APL Materials (2023)]. |
