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 ...

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 ...

Scientists have found a clever way to double the efficiency of thermoelectric materials — those that convert heat into ...

Scientists at EPFL have made a breakthrough in designing arrays of resonators, the basic components that power quantum ...

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 ...

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 solution was made possible by utilizing a special technology known as magnetic topological insulator Hall-bar devices. This latest invention addresses a major challenge concerning the ...

Topological materials can be categorized into several types, including topological insulators, topological superconductors, and topological semimetals. Each type exhibits unique electronic properties ...
