Abstract: The effect of the inter-Landau-band overlap on electron localization in integer quantum Hall systems is studied. A narrow band of extended electronic states is formed near each Landau band center due to interband mixing. However, these bands are greatly modified by the degree of interband overlap. The width of an extended-state band goes to zero when the interband overlap is below a critical value. This leads to a possible unified explanation to both scaling and non-scaling experimental results on plateau-to-plateau transitions.
