The study of electron spin in semiconductors has evoked considerable interest because of potential applications in spintronics devices and quantum-information processing technologies 1.The long ...

When an electron is excited from the ‘valence’ energy states of a semiconductor material to higher-energy conducting states, it leaves behind a hole. The electrostatic attraction between ...

Researchers studying currents in a room-temperature semiconductor wire have now observed a pair of odd spin effects thought extremely unlikely to occur in that material or at such a high temperature.
