Efficient Mobility Calculation for Quantum Dot Superlattices
The aim of this work is to calculate the electron mobility in a two dimensional periodic superlattice of quantum dots containing different-sized quantum dots. A simulation has been carried out using the tight binding method for calculating the energy levels and eigenstates of the periodic lattice. The different sized, non-periodic quantum dots are introduced as perturbed potential scattering centers and their effect has been included in the Fermi distribution to obtain a temperature dependent mobility tensor for easy comparison with experimental data.
