An ultra-fast water based switch has been developed by researchers. A short but powerful laser pulse converts the water into a metallic state in less than a tenth of a second. It's the fastest known switch speed of a Semiconductor so far.
The Ruhr Explores Solvation Cluster of excellence RESOLV published their findings in a journal.
Water behaves like a high-speed switch, thanks to a laser.
The operations of computers and phones are dependent on circuits. How fast a computer can run depends on how quickly a component can switch between states. Semiconductors are used in modern computers that make it possible to switch on and off. Claudius Hoberg says that they are limited in their speed.
He and his colleagues came up with a new approach to water-based circuits. The water in which the researchers had dissolved iodide ion is fanned out by a custom-made nozzle so that it becomes a flattened jet with a thickness of less than a millimeter.
Hoberg says it's like squeezing a gardening hose to make the jet of water broad and flat.
The water jet has a laser pulse directed through it. The properties of the water are similar to those of a metal because of the free electrons from the salt dissolved in the water. The water is turned into an ultra-fast switch when the laser pulse lasts less than 14 seconds.
Claudius Hoberg says a speed of 10 -12 seconds was recorded. The state of the water is being probed.
An ultra-fast liquid switch for terahertz radiation was presented. The DOI is 10.1063.
