Josephson Junctions

In this close-up of a Josephson junction chip, the junctions themselves lie beneath the four circles in the brown regions. Ultrafast switches, they can be turned on in as little as six trillionths of a second and are made of lead or niobium - both semiconductors - separated by a thin layer of insulating oxide. The narrowest lines in this photo are about 0.00001 inches wide. Actual size of the portion show here: 0.001 x 0.00112 inches.
