Physicists Created an 'Electron Lighthouse' That Steers Current With Light
Reported byScienceAlert ↗·Sourced by Goodlede
Physicists at the University of Michigan developed a device using two laser beams to control electron flow through a semiconductor without an external electrical field, creating a detectable 'ballistic' current steered by different wavelengths of infrared light.
The immediate applications remain theoretical; this is a foundational physics breakthrough with potential for future technologies.
