Wire four atoms wide conducts electricity


  • Wire four atoms wide conducts electricity

    WEST LAFAYETTE, Ind., Jan. 5 (UPI) -- Australian and U.S. researchers say they've created wires in silicon 4 atoms wide and 1 atom tall that carry electrical current as well as copper wires do.

    A team of scientists from the University of New South Wales, Melbourne University and Purdue University are engaged in research to develop future quantum computers in which single atoms are used for computation.

    "We are on the threshold of making transistors out of individual atoms," says Michelle Simmons at the Centre of Excellence for Quantum Computation and Communication Technology at the University of New South Wales. "But to build a practical quantum computer we have recognized that the interconnecting wiring and circuitry also needs to shrink to the atomic scale."
