NANORIBBON-BASED CAPACITORS

Capacitors based on stacks of nanoribbons and associated devices and systems are disclosed. In particular, a stack of at least two nanoribbons may be used to provide a two-terminal device referred to herein as a "nanoribbon-based capacitor," where one nanoribbon serves as a first capacitor electrode and another nanoribbon serves as a second capacitor electrode. Using portions of nanoribbon stacks to implement nanoribbon-based capacitors could provide an appealing alternative to conventional capacitor implementations because it would require only modest process changes compared to fabrication of nanoribbon-based FETs and because nanoribbon-based capacitors could be placed close to active devices. Furthermore, with a few additional process steps, nanoribbon-based capacitors may, advantageously, be extended to implement other circuit blocks such as nanoribbon-based BJTs or three-nanoribbon arrangements with a common connection between two anodes and a separate connection to a cathode.
