Summary

A team of researchers at Groningen University in the Netherlands has a new design for a superconducting transistor that uses a thin layer of gold in place of the so-called Josephson junction. While its speed still falls short of the best conventional devices, the novel design, to be published in Applied Physics Letters, gives it a key advantage over Josephson junctions: It can not only act as an on-off switch, but can also perform the other function of normal transistors--amplifying an incoming current.
