A Kronig‐Penney model with a constant electric field is used to examine the transmission properties of electrons in one‐dimensional disordered systems. Disorder is introduced into the system by assuming that the strengths of the δ‐function potential are random variables uniformly distributed. In particular the cases where the strength varies from 0 to W (barriers) and from −W to 0 (wells) are considered. Extensive results are presented and compared to other theories.
