Graphene has been hailed for a decades as a "wonder material." It's just one atom thick and has amazing properties for electrical and heat conductivity, as well as great strength, lightness, permeability and more.

From computers and batteries to lightbulbs, speakers and medical equipment, there's nothing it can't revolutionize. Or at least that's the theory. In the last decade, the number of graphene-related advances that have come true are in short supply.

Part of that is production. Making high-quality graphene in mass quantities still isn't easy, although there are a number of techniques being discovered.

The other problem, especially where computer-based advances are concerned, is a lack of a "band gap." Band gap means that if you only put a little electricity through the material it's non-conductive, but if you apply more electricity it becomes conductive.

Silicon has a band gap, which is why it's used for computer transistors. Graphene has no band gap. Even though it's fantastic at conducting electricity, it can't STOP conducting electricity.

To create a graphene-based transistor means multiple materials and a lot of fiddling. However, a brand new material could change that.
