Conducting nanocrystals (NCs) are effective components of thin film electronic devices. Devices consisting of spherical nanocrystals have been proven to be suitable components of such devices owing to their easy dispersity. However, complex geometries of the NCs and suitably controlled dispersion can facilitate large scale synthesis by reducing the requisite density of nanocrystals at the threshold of conduction. Here, simulation results are reported exploring different NC geometries. The results show that the conduction threshold is lowered depending on the complexity of the NC geometry. The effective interaction between the NCs is quantified by measuring the structure factor. The results are interesting from the synthesis point of view.
