Abstract
The electrostatic force plays an important role in charged particles’ self-assembly in inverted dielectric systems. The non-linear interactions between higher order multipoles are held responsible for the minimum energy equilibria formation of the dielectric particles. In this thesis, we use dynamic modeling of electrostatic interactions of charged particles and show that multiple nanoparticles can bind in minimum energy configurations exclusively by electrostatic forces that dominate at short distances in an inverted dielectric environment. It is also seen that the approximate model cannot explain the anomalous interactions for all binary clusters. Moreover, while an analytical model provides proper explanation for these stable equilibria due to nonlinear interactions of the charged dielectric particles, it also becomes extremely complex to understand for larger systems. Understanding these minimum energy configurations formation is crucial because they can serve as the building blocks in devising novel tunable materials and photonic surfaces.
