Researchers Simplify Switching for Quantum Electronics

A quantum cousin of the Hall effect could open the door to energy-efficient electronics, better sensors, and more-powerful quantum computers. Researchers have now broken a key barrier to its practical application by controlling the phenomenon electrically, rather than magnetically, for the first time. The Hall effect, discovered by physicist Edwin…

Spintronic Transistor Tech in a Vortex Beam

For decades, scientists have explored spintronics, which manipulate electron spin to theoretically operate more quickly and burn less energy than conventional electronics. Now researchers find that lasers can generate stable patterns of electron spins in a thin layer of semiconductor material, a discovery that may help lead to advanced spin-based…
