Cover Picture: Dendritic Nanowire Growth Mediated by a Self-Assembled Catalyst (Adv. Mater. 5/2005)



The dendritic nanostructures shown on the cover background were generated by self-assembled Mn clusters deposited from the vapor phase during vapor–liquid–solid growth of InAs nanowires. By carefully controlling the timing and amount of the Mn precursor, on p. 598 Lauhon and co-workers demonstrate a route to the formation of ordered hierarchical nanowire structures shown from various perspectives in the cover insets.
