Can material rivaling graphene be mined out of rocks? Yes, if...

Will one-atom-thick layers of molybdenum disulfide, a compound that occurs naturally in rocks, prove to be better than graphene for electronic applications? There are many signs that might prove to be the case. But physicists have shown that the nature of the phenomena occurring in layered materials are still ill-understood and require further research.
