New Real space method for calculation of physical properties of a disordered system
Rostam Moradian
Abstract
We introduce a new real space super cell approximation method for treating the electronic states of disordered systems. This method is general and allows both randomness in the on-site energies and in the hopping integrals. In the special case of randomness in the on-site energies only, this method is equivalent to the Non Local Coherent Potential Approximation (NLCPA) derived previously.
