Metallic nanostructures with controllable dimension and high aspect ratio provide an interesting alternative to carbon nanotubes for triode applications which require highly efficient and homogeneous field emission cathodes. Noble metal nanowires (NW) were electrochemically synthesized into the randomly distributed cylindrical pores of polycarbonate templates fabricated by GeV-ion irradiation, selective...
Field emission (FE) properties of randomly distributed free-standing Au nanowires (NW) were measured using thin metallic cathodes of about 50 mm2 in size with about 107 NW/cm2. The NW of diameter 120-260 nm and length 5-15 mum were electrochemically grown in cylindrical pores of etched ion-track polycarbonate membranes. The FE properties of the Au NW were investigated by local FESM measurements with...
