Most topological insulators are also excellent thermoelectric materials, since topological insulator and thermoelectric compounds share similar material features, such as heavy elements and narrow ...

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 ...

Lucky for this lot, electricity moves through metal too. Electricity, conductors and insulators work in a similar way. Copper allows electricity to pass through it quickly. It's a conductor.

Other insulators, which don’t allow electric current to flow through them, include wood and glass. Although I can see why they chose plastic to wrap electrical wires. I wouldn’t fancy using a ...
