Basically a graphene-like material made of boron, nitrogen and silicon. Analogs could make semiconductors a few atoms wide and three atoms thick.

Wasn't there an issue with the smallest size a conductor could be before hitting a barrier that would adversely affect the actual "conducting?"

The article sounds a bit fluffy. The issue here is that the flatness properties of graphene like substances can reduce one dimension a little.

This material if useful would take 10 to 20 years to be commercially viable, and reality is, that in space flight semiconductor weight is not that much of a problem, its the conductors that are really need to become more efficient.
