Schematic illustration of molecular level bonding mechanism between Ni particle and the fatty acid monolayer. STM image of nanoparticles on the top of the ordered octadecanoic acid array ((a) 65 nm × 65 nm/ = 0.5 nA, = 900 mV/). High resolution STM image of individual Ni particle ((b) 25 nm × 25 nm/ = 0.5 nA, = 900 mV/) and the ordered fatty acid template on the same sample ((c) 20 nm × 20 nm/ = 0.5 nA, = 900 mV/).
