UW Madison News Semiconductors have traditionally relied on electron for the on/off switches to record and process information. The next iteration of computing, including low-power devices and quantum computers, is shifting to “spintronics,” will rely on new types of semiconductors that use a fundamental property of electrons called spin instead of electric charge.
