Topological insulator waveguides Engineers at the University of Pennsylvania and Polytechnic University of Milan applied topological insulators to photonic chips to make reconfigurable waveguides. In topological insulators, charged particles can flow freely on the material's edges but can't pass through the interior. For photonics, topological insulators with edges that could be redefined m... » read more

Mixing topology, spin MIT researchers are studying new compounds, such as topological insulators (TIs), which support protected electron states on the surfaces of crystals that silicon-based technologies cannot as part of the pursuit of material platforms for the next generation of electronics. They report new physical phenomena being realized by combining this field of TIs with the subfiel... » read more

White graphene can take the heat According to researchers at Rice University, 3D boron nitride structures excel at thermal management for electronics. Rice researchers Rouzbeh Shahsavari and Navid Sakhavand have completed the first theoretical analysis of how 3D boron nitride might be used as a tunable material to control heat flow in such devices. In its 2D form, hexagonal boron nitride... » read more

Ballistic transport in graphene Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance even at room temperature in a process known as ballistic transport, according to researchers at Georgia Tech. Ballistic transport is the process by which electrical res... » read more
