A comment on IBM says it has made working versions of 7nm chips. Parent comment
C has a 5.5eV band gap while Si has a 1.1 and Ge has a 0.67
Whats bandgap? The energy difference between a conductor/insulator in a semi-conductor. https://en.wikipedia.org/wiki/File:Bandgap_in_semiconductor....
The only real reason to switch to carbon chips is noise reduction at the 4nm node (if we ever go that far, we're getting into Long X-Rays at that point for lithography).
Also 4nm node will only be ~16-18 carbon atoms wide.
