Topological insulators are a relatively new type of quantum material that has insulating properties on the inside, but have conductive properties on the outside. To use a Southern California ...

A groundbreaking study led by researchers from Southeast University, the Chinese Academy of Sciences, the University of Hong Kong, and the University ...

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 ...

Experiment has now proved the existence of the predicted three-dimensional 'topological insulator' in the semiconducting alloy Bi 1−x Sb x. One of the triumphs of quantum mechanics in the ...

This is just one reason why topological insulators are one of the hottest topics in physics right now. Flatland has a rigid social hierarchy in which social class depends on the number of sides a ...

An international team has succeeded in producing new, efficient thermoelectric materials that could compete with state-of-the-art materials, offering greater stability and lower cost.

The electronic band structure of topological materials is completely different from that of conventional materials, leading to phenomena not seen in typical materials such as insulators, conductors ...
