Graphene origami opens up new spintronics features

"(Phys.org) - Despite graphene's many impressive properties, its lack of a bandgap limits its use in electronic applications. In a new study, scientists have theoretically shown that a bandgap can be opened in graphene by folding 2D graphene sheets origami-style and exposing them to a magnetic field. In addition to opening up a bandgap, this method also produces spin-polarized current in the graphene sheets, making them attractive for spintronics applications.

The scientists, A. T. Costa, et al., from institutions in Brazil, Ireland, Singapore, and the US, have published their paper on graphene origami in a recent issue of EPL."
