Abstract

This paper focuses on the electrodeposition of high density nanowire arrays in porous anodic aluminum oxide (AAO) templates. A two step anodization technique was used to develop a template for Bi1-xSbx nanowire growth directly on Si substrates. Uniform pores with virtually no grain boundaries were achieved. Fundamental electrochemistry experiments on Bi3+, Sb3+, and both cations in dimethyl sulfoxide (DMSO) were carried out to characterize the ideal chronopotential pulse and to determine the thermodynamic, diffusion and mass transport issues when plating Bi1-xSbx into nano dimension pore structures. Such chronopotentiometry resulted in uniform nanowire growth within porous channels of the AAO template.
