A single-molecule room-temperature transistor made from 14 atoms

Phosphine stands for the compound PH3.

That's not a nitpick. "ethyl-4-(methylthio)phenyl phosphine atoms" can go right next to "dihydrogen monoxide atoms" on the list of things that aren't.

Well, sort of. A transistor is something with an 'on' state and and 'off' state (and a whole range in between for analog purposes). This one apparently also has an 'on' and an 'off' state but the mechanism by which they change the state does not really spell 'transistor' though if there is an electrical way to do it it might qualify.

The relevant bit from TFA:

"The device can reliably switch from insulator to conductor when charge is added or removed, one electron at a time (known as “current blockade”)."

So it is more like a FET and the charge placeholder would be the gate. It's not clear to me whether or not they had anything wired up to that spot or how they added or removed the electrons.

I wait for the 13 atoms version.
