Scientists have developed a device called a Josephson junction which can successfully split and recombines the copper pairs of electrons during superconductivity. In traditional superconductors, electrical current faces no obstruction as the copper electrons combine to make ‘Cooper pairs’. The device contains two aluminum electrodes and the two electrodes are bridged by two semiconductor nanowires. Researchers claim that the device may help to explore a unique form of superconductivity and could be useful in developing quantum computers.
