Investigating the effect of disorder on density of states of graphene nano-ribbons

Authors

Abstract
In the present paper, we calculate the effect of disorder on the density of states and localization of eigenstates of zigzag and armchair nano-ribbons. Both Anderson disorder model and quantom percolation are considered. The eigenstates of the disordered hamiltonian is calculated in a tight–binding approximation and the localization of eigenstates are characterized using the inverse participation ratio (IPR). Based on IPR data, the transport properties in the presence of disorder is discussed.
