Scientists built a chip without semiconductors

Remember those old-timey room-sized vacuum-tube-powered computers with less processing power than your smartphone? That tech might be making a comeback, thanks to work from scientists from UC San Diego. They've built the first semiconductor-free, laser-controlled microelectronics device that uses free electrons, much as vacuum tubes do. The research could result in better solar panels and faster microelectronic devices that can carry more power.
