15,000 beams of light: Pens that write with light offer low-cost, rapid nanofabrication capabilities
One city skyline is dazzling enough. Now imagine 15,000 of them. Researchers have done just that -- drawing 15,000 identical skylines with tiny beams of light using an innovative nanofabrication technology called beam-pen lithography. BPL uses an array of pens made of a polymer to print patterns over large areas with nanoscopic through macroscopic resolution. The method could do for nanofabrication what the desktop printer has done for printing and information transfer.
