(85f) Self-Organization of Nanowires from Nanoparticles

It was previously established experimentally that, semiconductor nanoparticles possess significant dipole moment. Under specific conditions, such as removal of substantial portion of the stabilizer layer, the dipole moment affords self-organization of NP in chains and later in nanowires. The mechanism of the formation of dipole moment in seemingly anisotropic nanoparticles was established. The mechanism of the self-organization was modelled by Monte-Carlo method. Parameters of the nanoparticles such as total charge and dipole moment were calculated. It is concluded that at short separations, the interactions between the nanoparticles are unusually strong.
