First graphene semiconductor was created

This is a most excellent place for technology news and articles.
Not quite I guess, that wafer is what's needed for chip making but from reading the paper it looks like they were just trying to figure out how to make the band gap of the graphene just the right size. It says their next step is trying to adapt silicon chip making techniques to this new material. Terracing I guess to start?
