A co-author makes bolder claims. I guess in context, the meaning is different, more of a metaphor. And even though, diodes can form some logic gates (diode-logic).

But what's really interesting is the size of 14 atoms in the core of the molecule. How does that compare to 14 nm feature-sizes of different FET-technologies?

A rule of thumb: a hydrogen atom is 0.1 nm in diameter.

A caveat to keep in mind, diatomic hydrogen is not 0.2.

EDIT: Actually the van der wahl diameter of Hydrogen is about 240pm. 0.12nm is about the radius.

In the article it says that the cluster is around 0.5 nanometers in diameter.

Article said that the inorganic core was 14 atoms. The graphic showed a much larger organic molecule wrapped around the core.

It is unclear whether 0.5 nm refers to the inorganic core or the entire molecular complex.

It is also possible that the organic molecule changes geometry to open or close the conductive channel, so it could have variable diameter.
