Topological insulators (TIs) are a class of materials with surfaces that host a new quantum state of matter and are insensitive to contaminants, defects and impurities. Surface electrons in TIs behave ...

This was done by applying high pressures. NiS2 is a Mott insulator at ambient pressure. The strong Coloumb repulsion between electrons causes a grid-locked state in which all electrons are localised ...

It hardly conducts any electricity at all, so we can say it’s an electrical insulator. Inside the plastic, all the electrons are tightly bound to the atoms, so the charges cannot move very far ...

Electric charges on the boundaries of certain insulators are programmed by topology ... same space with little or no interactions (such as electrons in a 0D quantum dot), and quantum mechanics ...

Discover the science behind mirrors and glass, from electron behavior to topological materials, explained by IIT Kanpur professor.

as in conventional insulators, but from their lack of mobility due to repulsive interactions between electrons. Although theoretically conductive, these materials thus behave as electrical insulators.

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 ...

Noble gases such as helium and neon are poor conductors of electricity, so we call them electrical insulators. Copper and ...

Within the top gate barrier (which is otherwise an insulator), a very narrow passageway which conducts electrons normally (N), can link the superconducting (S) panels on either side of the top gate.
