Existing vacuum tube tech required high voltages, high temperatures, or powerful lasers to knock electrons loose, all of which would be very difficult at the small scale required for microelectonics. To get around this, the team at UC San Diego constructed a gold “mushroom” nanostructure with adjacent parallel gold strips. Using a small amount of voltage (10 volts) and a low-powered laser, they were able to dislodge electrons from the gold metal.

The innovative system created by the researchers produced a 1,000 percent increase in the conductivity of the system, enough “to realize on and off states, that is, the structure performs as an optical switch,” the study reports.
