The direction of free electron flow is from the negative terminal, through the conductor, to the positive terminal. ... A switch is used to turn a circuit on (closed) and off (open).

They’ve essentially toggled the electron highway signs with an external magnetic field. This elegant control over band asymmetry might lead to low-power, high-speed data storage based on ...

Circuit City Stores Inc., the nation's second-biggest consumer electronics retailer, reached an agreement with liquidators today to sell the merchandise in its 567 U.S. stores after failing to ...

Researchers at Dartmouth have built the world’s first superfluid circuit that uses pairs of ultracold electron-like atoms. (Image: Robert Gill, Dartmouth College) “Much of modern technology revolves ...

Semiconductor nanostructures based on two-dimensional electron gases (2DEGs) could form the basis of future devices for sensing, information processing and quantum computation. Although electron ...

The closed-circuit case is potentially different; if strong interlayer correlations are present, relatively large oppositely directed currents, mediated by exciton transport, might flow in the two ...
