Earlier this year I put together a very quick post on the wonders of graphene. What was left unsaid was all the difficulties that are currently part of graphene including its nearly useless as graphene transistors (for computation) / lack of band gap.
The latest “new” material, (…) — which has actually been used for decades, but not in its 2-D form — was first described just a year ago by researchers in Switzerland.
The lack of a bandgap, Wang explains, means that with a switch made of graphene, “you can turn it on, but you can’t turn it off. That means you can’t do digital logic.” So people have for years been searching for a material that shares some of graphene’s extraordinary properties, but also has this missing quality — as molybdenum disulfide does.
