摘要：

We report a simple method to generated metallic nanowire arrays. By irradiating thin organic films with embedded silver or gold nanoparticles with series of ultrashort laser pulses, wire arrays containing more than 30 nearly parallel wires several microns in length are formed. The individual nanowires are between 100 and 200 mn wide with equal line space ratios, significantly smaller than the laser wavelength used. The wire direction correlates to the linear polarization of the laser pulses. This structural dependence on the laser polarization is mirrored in corresponding anisotropic optical and electrical film properties. (C) 2001 American Institute of Physics.
