If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...

Spin electronics, or “spintronics” promises to revolutionize computing. We’ve covered numerous breakthroughs in the field including controlling the spin of electrons, manipulating single electrons ...

Physicists report new insights into the behavior of electrons on the surface of a topological insulator, a class of material with unique properties that challenge some of the oldest laws of physics.

A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum ...

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental science and potential quantum technologies. For decades, quantum ...

For several decades, a central puzzle in quantum physics has remained unsolved: Could electrons behave like a perfect, ...

Solar panels capture sunlight and convert it to electricity using photovoltaic (PV) cells like the one illustrated above. Such cells, which can power everything from calculators to cars (our example ...

Table 1 Properties of 2DEG samples, measured in a Hall bar configuration. Sample A was grown by the commercial grower IQE. Sample B was grown by H. Shtrikman. Sample C was grown by L. N. Pfeiffer and ...

Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to packages of electrons. One coulomb of charge is a package equivalent to ...
