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.
