RICHMOND, VIRGINIA-- At the International Symposium on Cluster and Nanostructure Interfaces here last week, an electrical engineer described a new microscopic patterning technique capable of creating arrays of plastic pillars, each less than a thousandth of a millimeter across. Cheap, fast, and versatile, the patterning scheme could help create novel plastic displays and electronic devices. The pillars themselves could not only be used as wires in plastic electronics, but could also direct the growth of other materials, such as metals and semiconductors, into regular patterns.
