Other insulators, which don’t allow electric current to flow through them ... Although most non-metals are poor conductors, graphite is an example of a non-metal which is a good electrical ...

Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...

Electric charges on the boundaries of certain insulators are programmed by topology ... if quantum mechanics had applied in Flatland: for example, two or more quantum objects can simultaneously ...

They are: Substances that allow electricity to pass through them easily are called ‘conductors’. Metals, human and animal bodies, earth, etc. are examples of conductors. Insulators do not ...
