Real and virtual charge carriers used to create ultrafast logic gates

Caption

Synchronized laser pulses (red and blue) generate a burst of real and virtual charge carriers in graphene that are absorbed by gold metal to produce a net current. “We clarified the role of virtual and real charge carriers in laser-induced currents, and that opened the way to the creation of ultrafast logic gates,” says Ignacio Franco, associate professor of chemistry and physics at the University of Rochester.
