Stanford University scientists have made an electronic device of new superconducting substances, a breakthrough that could speed the development of superfast computers, scientists at Stanford University say.
The announcement is the most recent in a series of breakthroughs around the country on superconductivity, the transmission of electricity without resistance.
It addresses a key issue--the temperature at which scientists can use superconductive circuits, which are extremely fast electronic links. Until recently, superconductivity could be performed only at extremely cold temperatures; recently, laboratories in Switzerland, China and the United States developed materials that work at higher temperatures.
Stanford University's applied physics department announced that it had shaped those materials into thin films to create prototype electronic devices. The Stanford scientists, headed by Theodore H. Geballe, said they made superconducting films that are just 1,000 to 2,000 atoms thick by condensing a vapor of lanthanum strontium copper oxide onto a flat surface.
