(PhysOrg.com) -- "Graphene offers a lot of interesting potential applications for nanoelectronics," Florian Banhart tells PhysOrg.com, "but there is no band gap. This is a well-known problem. Without the band gap, switching ...
Researchers from the University of Twente proved that germanene, a two-dimensional material made of germanium atoms, behaves as a topological insulator. It is the first 2D topological insulator that consists of a single element. ...
