Researchers have developed the 1st semiconductor-free optically controlled microelectronic device.

Researchers at the University of California San Diego (UCSD) have developed the first optically controlled microelectronic device that doesn’t use a semiconductor . The research allows for the design of microelectronic devices that work faster and can handle higher power loads, as well as paves the way for more efficient efficient solar panels, researchers said. Current microelectronic devices, such as transistors, are limited in capability by the properties of components such as semiconductors, which can impose limits on a device’s conductivity, or electron flow. That’s because semiconductors have what’s called a band gap, meaning they require a boost of external energy to get electrons to flow through them. This limits electron velocity, as electrons are constantly colliding with atoms as they flow through the semiconductor. To help overcome these limitations, a team in ...
