Copper Nano- and Micro Wires Electrodeposited in Etched Cellulose Nitrate and Makrofol KG Nuclear Track Detector

Abstract

Cellulose Nitrate and Makrofol KG nuclear track detector foils of 96μm and 20μm thicknesses were irradiated with 238U ions (kinetic energy 17.7 MeV/u, fluence 105 ion/cm2) and 208Pd (kinetic energy 14.0MeV/u, fluence 105 ion/cm2), respectively. By etching of damage trail caused by the ion, templates containing conical pore were prepared. By electrochemical deposition of copper in homemade design electrolytic cell, conical wires were obtained. The electric current recorded during electrodeposition reflects the geometry of the pore. The lengths of wires were 96μm and 20μm, corresponding to the thickness of membranes. X-Ray Diffraction analysis indicated that texture and orientation of Cu wire were polycrystalline.
