Unzipping graphene nanotubes into nanoribbons: Elegant mathematical solution explains how flow of electrons changes when carbon nanotubes turn into zigzag nanoribbons

In a new study scientists provide a detailed analysis of how the flow of heat and electrons is affected at the interface between an 'armchair' shaped carbon nanotube and a zigzagging nanoribbon made up of a single-layer carbon honeycomb sheet of graphene. Applications of this method can help us understand the propagation of electrons and thermal flow in graphene and similar materials for electromagnetic devices.
