A theoretical study of resonant interband tunneling in quantum well structures in the uniform-field model (Zener model) is presented. The analysis is carried out in the framework of a simplified two-band Kane's model. It is shown that the transmission coefficient, T ( E ) , as a function of the electron energy exhibits a well defined resonant structure. Some interesting properties of T(E), as well as of the corresponding peak values and of the resonance energies, as a function of the well width and of the applied electric field are reported.Une etude thkorique de l'effet tunnel resonnant inter-bande dans des structures de puits quantique en utilisant le modele de champ uniform (modele Zener) est present&. L'analyse est realist: dans la structure d'un modele simplifiee a deux bandes, modtle de Kane. I1 est montre que le coefficient de transmission T ( E ) comme une fonction de l'energie electronique present une structure resonnante bien definie. Quelques proprietes interessantes de T ( E ) de mime que les valeurs de pics et des energies de resonance comme fonction de la largeur du puits et du champ tlectrique applique sont rapporte.
