Researchers from the US, Singapore, Brazil and Ireland have theoretically shown that if you fold a graphene sheet in a fin-like structure and expose it to a magnetic field you open up a bandgap. This will also produce spin-polarized current, which should make it useful in Spintronics applications.

The researchers say that this folding can be easily achieved by depositing graphene on a substrate with periodic trenches.
