    Graphene is undeniably one of the most miraculous materials ever discovered — it’s probably the answer to our battery dependency woes, amongst other things — but it lacks one very important feature that semiconductors need: a reliable bandgap. Semiconductors, by definition, sometimes insulate and sometimes conduct, depending on how much voltage you run through them. The voltage difference required to switch between insulating and conducting states is called the bandgap — and graphene doesn’t have one. Molybdenite, on the other hand, has a bandgap right in the sweet spot for everyday computer chips.
