His theoretical research concerns the electronic structure and spectroscopy of exotic quantum states of matter such as topological insulators and high temperature superconductors. His research effort includes the search for new topological materials which have opened new routes for generating novel phases of matter with huge potential applications in spintronics, information and energy technologies.
Silicene is a one-atom-thick 2D crystal of silicon with a hexagonal lattice structure that is related to that of graphene but with accessible spin-orbit coupling strength and with atomic bonds that are buckled rather than flat. These subtle differences could be exploited to build electrically-gated silicene devices that generate and control spin-polarized currents with near perfect efficiency.
