Selective adsorption of metal nanowires on molecularly patterned substrates using surface-to-volume ratio-dependent strategies

초록

We demonstrated the effect of the surface-to-volume ratio (S/V) in the adsorption of metal nanowires (NWs) on molecularly patterned substrates by preparing three different groups of Au NWs with similar lengths (3-4 mu m) but different diameters (350, 80, and 35 nm). The three NW groups showed clearly distinct adsorption characteristics, and hence require different adsorption strategies based on their interaction with the substrate. We also showed that the effect of NW surface functionalization was considerably dependent on S/V. Our work will help in selecting the appropriate adsorption strategy in accordance with the S/V of the NWs. (C) 2014 The Japan Society of Applied Physics
