摘要：

By using Monte Carlo simulation method, we studied the influence of the localization length as a function of the disorder and eigenenergy in disordered system. The results derive that electronic states of system exhibited localization phenomena with the increase of degree of disorder and the localization length can be reduced gradually. Moreover the degree of electronic localization is different for different energy eigenvalue, the quasi extended state appears at the center part of energy band and quasi-metal behavior emerges in the disordered system.
