Effects of Polarization Direction on Removal Characteristics of Silver Nanowire Transparent Conductive Film by fs Pulsed Laser

Abstract

Silver nanowire transparent conductive film is expected as a new material for transparent electrodes because of its superior flexibility and electrical conductivity with high transparency at visible wavelength. Laser beam processing has been widely used for these application, and laser beam has the unique characteristic as an electromagnetic wave. Its feature has a great influence on laser-material interaction. However, these mechanism have not yet been clarified. Therefore, the polarization characteristics indicated by electric and magnetic fields were discussed, and effects of polarization direction on removal characteristics of silver nanowire transparent conductive film were investigated by using femtosecond pulsed laser with linear polarization.
