Abdulaziz Alhaidari from the Saudi Center for Theoretical Physics in Saudi Arabia claim that if you reduce the number of space-like dimensions in graphene from two to one, the mass-less equations that describe the behavior of electrons and holes will change to include a term for mass. In effect, compactifying dimensions creates mass.
The idea is that you roll the Graphene up, and This changes the sheet into a tube that is effectively 1-dimensional, at least as far as the electrons and holes are concerned.
