Effects of an impurity sheet in the middle of the well on resonant tunneling are theoretically analyzed in double‐barrier structures. It was found that the energies of the even‐resonance states shift toward higher levels and the states get broader as the height of the perturbation potential strength increases. There are no changes in the odd‐resonance states because of the nature of their wave functions. © 1995 American Institute of Physics.
