An illustration of the 'electron lighthouse' created at the University of Michigan. (Yiming Gong) The flow of electrons powers our modern lives. From household conveniences like the indispensable air ...

With support from the U.S. National Science Foundation, the researchers used two colors of light to produce an organized flow of electrons through a semiconductor. They could also change the direction ...

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we ...

A team of researchers at the U.S. National Institute for Standards and Technology has found that electron current flow direction produced by the photon-drag effect is dependent on the environment in ...

An atomic force microscope can be used as a single-electron current meter, according to new experiments by researchers at IBM. The technique, which measures the energy levels of single molecules on ...

Scientists have created an “electron lighthouse” that uses laser light to launch and steer electrons through a semiconductor without an applied electrical field. The quantum effect could eventually ...
