In this work we use the Kronig-Penney model with delta function potentials as a one dimensional model of solid in order to study the effects of structural and chemical disorder in the plane wave representation. Structural disorder takes into account the variation on the potential position and chemical disorder is produced by changing the potential intensity and keeping fixed the distance between potentials. LMC statistical complexity measure and electron flux are used to evaluate the disorder effects. Both of them, structural and chemical disorder, produce the maximization of the electron complexity and the minimization of the corresponding electron flux which indicates the inhibition of electron transport.
