...toward the other goal of superconductivity researchers, pushing the phenomenon into a practical temperature range, was even slower. By 1973, some 62 years after Kamerlingh Onnes had found superconductivity in mercury at 4.2 K, scientists had upped the temperature to only 23 K, using an alloy of niobium and germanium. After 1973: no improvement...
...much sought-after goal proved to be elusive. In the early 1970s scientists found an alloy of niobium and germanium that lost all resistance at 23 K. Then, last April, a group at the IBM Zurich Research Laboratory in Switzerland announced development of a compound of barium, lanthanum, copper and oxygen that appeared to begin the transition to superconductivity...
...demonstrated a small, simple device that can do many of the jobs now done by vacuum tubes. Called a "Transistor," it is a slim metal cylinder about an inch long. Inside are two hair-thin wires whose points press, two-thousandths of an inch apart, on a pinhead of germanium...
...wherever they were, those new stars should have been extremely bright. But strangely, none could be found. Then Low learned from a visiting astronomer that R Mon seemed to be emitting an abnormally large amount of infra-red radiation. He decided to check on the star with his germanium bolometer, an extremely sensitive infra-red measuring device of his own design (TIME...
...whose eleven divisions concentrate on electronics and also turn out a range of products from heavy multiconductor cables to printing equipment. All the excitement is over one division, the Semiconductor branch. It put Fairchild on the ground floor in miniature silicon transistors, which are more effective than the original germanium variety; last year Fairchild had 30% of the booming U.S. market for silicon transistors. Fairchild's prize division also accounts for one-third of the market for integrated circuits, which are fleck-sized components that do the work of many transistors, and a series of them hooked together could...
