Electrodeposition of monodispersed Fe nanocrystals from an ionic liquid.

Monodispersed Fe nanocrystals up to approximately 2 nm thick, approximately 50 nm wide and approximately 120 nm long have been electrodeposited from the ionic melt AlCl(3)-1-methyl-3-butylimidazolium chloride [AlCl3-[MBIm](+)Cl(-)] at room temperature on Au(111) and have been characterized in-situ by electrochemical scanning tunneling microscopy.
