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 ...

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.

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 ...

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 ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

Phononic circuits are emerging devices that can manipulate sound waves (i.e., phonons) in ways that resemble how electronic ...

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 ...
