Nous étudions dans ce travail les effets du désordre sur les états électroniques du polyacetylène. En effet, les impuretés et les différences d'environnement vont entraîner des fluctuations sur les valeurs des énergies des orbitales (désordre diagonal) et sur les intégrales de transfert (désordre non diagonal). Nous discutons les conséquences de chaque type de désordre et leur importance relative, pour des valeurs réalistes des paramètres du désordre.In this work, we investigate the effects of disorder on the electronic states of polyacetylene. In effect, due to the impurities and variable environment, we would expect some fluctuations in both the self energies (diagonal disorder) and the hopping integrals (off-diagonal disorder). The conse...
