Abstract

Patterned micro-and nanowires composed of Iron Oxide (FexOy) were electrochemically deposited from an ionic liquid solution of choline chloride (ChCl) and urea, using ultrananocrystalline diamond (UNCD) ™ templates originally developed for Electroplate and Lift (E&L) Lithography. The wires were electroplated under varying rigor of anhydrous and inert atmosphere techniques, at voltages of either -2V or -5V vs. an Al/Al(III) reference electrode. The morphology of the deposited FexOy wires was studied by scanning electron microscopy (SEM), while their oxygen content was evaluated using energy dispersive spectroscopy (EDS). By using sublimed grade reagents and minimizing exposure to atmospheric water vapor and oxygen, the oxygen content of the electroplated wires decreased from 15 at% to 5 at%.
