Researchers from Switzerland's EPFL lab discovered that a material called Molybdenite (or MoS2) can be used as an alternative to Silicon - and might be a better than Graphene. Molybdenite is a common mineral - but hasn't been studied for electronics yet.

Molybdenite is a two-dimensional material, very thin and light - and can be used to make transistors, LEDs and solar-cells, according to EPFL Professor Andras Kis.Molybdenite also have an energy gap, unlike Graphene - which is an advantage for electronics.
