Today, laser physicists have achieved the ability to precisely control electrons in a semiconductor with picosecond accuracy. This breakthrough, which was published in Nature Physics, is a key step towards the development of ultrafast optoelectronic devices. The ability to precisely control electrons in femtoseconds (quadrillionths of a second) allows for a new way to manipulate electrons in semiconductors. This means that laser physicists can now create photoinjection devices that are ultrafast and highly efficient. This could open the door to a new generation of devices that could revolutionize the way we use electricity.
