University of Utah engineers demonstrated it is feasible to build the first organic materials that conduct electricity on their molecular edges, but act as an insulator inside. Called organic ...

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 ...

A computer model shows interference patterns formed by electrons traveling across the surface of a topological insulator. (Image: Ali Yazdani, Science Source) In 2005, condensed matter physicists ...

A new method by Penn State researchers conveniently changes the direction of electron flow in materials that exhibit the quantum anomalous Hall (QAH) effect — a phenomenon in which the flow of ...

The rubber around this wire is an insulator. Some materials do not allow electricity to pass through them. These materials are known as electrical insulators. Make a list of all of the objects ...
