Nanopore size was varied from 200 to 15 nm in diameter. Pt-Pd alloy film was sputtered on one side of PC filter and then used as cathode in 0.6 M CuSO4 aqueous solution (pH = 2). Potentiostatic electrodeposition at - 400 mV vs. Cu reference electrode was conducted in two kinds of electrolytic cell configurations, Cathode over Anode (C/A) and Anode over Cathode (A/C). It was also engaged in a strong magnetic field. The transient variation of cathodic current clearly showed four stages in both cell configurations. In Stage 2, the cathodic current increased in A/C configuration, while it decreased in C/A. The difference of cathodic current variation between two configurations was smaller with smaller sized pores. Superposition of magnetic field introduces much shorter duration period of the second stage. Cu nanowire arrays were successfully electrochemical-processed with the aspect ratio of 50 to 400. Furthermore, 15 nm diameter Cu nanowire was confirmed with the lattice image pattern by TEM (Transmission Electron Microscopy) technique. Much better crystallinity may be expected by controlling the gravitational level as well as the magnetic field flax, besides the improved template technique., 資料番号: AA0048095013}, pages = {55--58}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Effects of gravitational level & magnetic field flux on dendritic growth process of electrodeposited copper}, year = {2005} }
