Abstract

Bismuth nanoparticles, protected by two types of capping ligands, 1-dodecanethiol and ethylene diamine tetra-acetate, were probed by TEM and STM at 80 and 300 K. Both types of nanoparticles show temperature-dependent structural fluctuations leading to pronounced changes in their anisotropic conductance properties. We show that the different capping ligands dramatically alter the structural dynamics in these particles. This finding suggests that molecular control of structural and consequently electronic switching in anisotropic nanosystems is feasible.
