Topological insulators are materials that are insulating in their interior but can support the flow of electrons on their surface. The underlying cause is time-reversal symmetry: their physics is ...

On the periodic table, semiconductors (also known as metalloids) crop up along a diagonal line between conductors and insulators. Noble gases such as helium and neon are poor conductors of ...

A kind of umbilical cord between different quantum states can be found in some materials. Researchers at TU Wien have now shown that this "umbilical cord" is generic to many materials. It is a ...

Electronic and electrical engineers create the technology at the heart of our modern world, from high speed communication networks, to off-shore renewable power generation, to future driverless ...

Electronic and electrical engineers invent and create the technology that typifies today's high-tech society, from devices and systems that monitor our health and well-being, to global data networks, ...
