An efficient model for evaluating current in silicon nanocrystals

In this paper we present an efficient model for current calculation through silicon nanocrystals. The model uses self consistent field approach to calculate the evolution of transmission spectra and Landauer formalism for current calculations. We implemented the split in spectra for different spin so that the model works in case of coulomb blockade. A few simulations were performed using a physical simulator to extract parameters to be inserted in model. The current voltage characteristics were calculated from the model for structures with different geometry and coupling strength between the lattice and contacts. The results from the model show good accordance with those from physical simulator and are obtained with more than two orders of magnitude speed up.
