It really looks like they are trying hard to scale a system that is simply explained away by a simpler model... From TFA:

  The switching behavior they see could just be an electron hopping on and off a quantum dot, perhaps one formed incidentally by part of the wirelike region, Legg says. “This is exactly what you could get from a quantum dot.”

I won't pretend I have a deep understanding of any of this, so the only parameters I can judge is the consensus of people that do, and these people aren't too happy about the claims being made.

It sucks to have your work made redundant, so it's hard to understand if their critism is founded or just sour grapes.
