Description

Mo6S9-xIx (MoSIx) nanowires have been known to easily bond to golden nanoparticles (GNPs) due to their sulfur terminated ends. Solution-processed attachment was used for connecting MoSIx nanowires as leads to GNPs. We have recently observed irregular self-assembled networks consisting of small nanoparticles and thin MoSIx nanowires (<2.5 nm in diameter) that span on a scale of several tens of micrometers. One such network has been analyzed by measuring heights of particles and number, diameter and orientation of nanowires connected to them. Results confirm that the bonding between nanowires happens more easily via nanoparticle than without it. We have also monitored this network by taking its topographic picture every few weeks for the last six months and degradation of the network with time has been observed – the nanoparticles have been reduced in size and nanowire diameter has substantially decreased.
