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.
