Copper nanowires to brighten flat-panel displays
Researchers at the University of Illinois in Urbana Champaign have developed a simple process to grow upright copper nanowires on different surfaces. The nanowire arrays could find use in field-emission displays, a new type of display technology that promises to provide brighter, more vivid pictures than existing flat-panel displays. In such an application, the nanowires would be used to fire electrons at phosphor particles on a screen, lighting them up.
The new manufacturing method, developed by Kyekyoon Kim and Hyungsoo Choi, leads to copper nanowires between 70 nanometers and 250 nanometers wide. The researchers can use the process to grow the nanowires on various surfaces, including silicon, glass, metal, and plastic. They describe the nanowire array and demonstrate a prototype field-emission display in an online Advanced Materials paper.
