Davis group finds magnetic disorder in topological insulators

To better understand topological insulators (TIs) and why they weren't living up to their potential Seamus Davis's group at Cornell and Brookhaven National Lab studied them with their scanning tunneling microscope. What they found is the magnetic disorder at the surface was preventing the smooth flow of electrons.
