"increasing energy efficiency and speed without silicon... control magnetization of the atoms of individual sublattices through selective interaction with structural defects of substrate... information transmitted as spin currents... reduces power consumption and increases speed of information transfer... strengthening spin-orbit  explained by presence of gold atoms under graphene. At certain ratio of magnetic and spin-orbit interaction... move from familiar state of graphene to novel, topological one"
