Nanowires are tiny crystalline fibers, typically less than one hundred nanometer across, and thousands of nanometers long. Nanowires are grown starting with a tiny bead of liquid gold or other metal that is placed in a vapor of the nanowire material. The material is attracted to the beads and grows into a long thin spike. Nanowires display an array of physical properties that depend not only on the material but also on their diameter, for example they conduct electricity differently than a large piece of the material they are made with. Peidong Yang a possible candidate for the Nobel prize in physics, has examined many different types of nanowires and their properties, including the ability to conduct a laser beam down its extremely narrow diameter. They can be used in quantum computers, as when two nanowires cross it creates a quantum dot; in flexible solar cells; and in tiny self-contained sensors.
