Important material properties can be explained at the level of quantum physics - for example, whether a material conducts electricity or not. Analysing such quantum states has now revealed that there ...

Now, the outside of electric wires are usually covered in plastic because it’s a very poor conductor. It hardly conducts any electricity at all, so we can say it’s an electrical insulator.

Metals are generally good conductors, but some materials such as wood, rubber, and plastic are not good at conducting electricity. These materials are called “insulators”. Electricity does not move ...

Noble gases such as helium and neon are poor conductors of electricity, so we call them electrical insulators. Copper and other metals are conductors, which allow the free movement of electrons ...

Mott insulators can become conductors by changing certain parameters ... Their unique properties, driven by strong electron-electron interactions, make them an intriguing subject of study for ...

Scientists have developed a hybrid material that switches between conducting and insulating states while maintaining ...

Scientists have used topological insulators to demonstrate ... h is Planck's constant and e is the electron charge. For the topological conduction channels, all phase coherent trajectories ...

The discovery of a dual topological insulator introduces a new method for creating topological flat minibands through electron interactions, which offer a promising platform for exploring exotic ...

In an insulator the Fermi energy lies in the bandgap between the minimum of the conduction band and the ... host (or the edge of a 2D host) and new electron states appear at these boundaries.

As expected the valence band is fully filled in graphene, whereas the conduction ... non-interacting electron picture becomes invalid, leading to a metal–insulator transition 3.

If you can’t answer the riddle, don’t feel bad. Metal conductors usually conduct electricity and heat. Usually, that’s true, but researchers at the Department of Energy’s Lawrence Berkeley ...
