First semiconductor free microelectronic device


Engineers at the University of California San Diego have fabricated the first semiconductor-free, optically-controlled microelectronic device. Using metamaterials, engineers were able to build a microscale device that shows a 1,000 percent increase in conductivity when activated by low voltage and a low power laser. 

The discovery paves the way for microelectronic devices that are faster and capable of handling more power, and could also lead to more efficient solar panels.
