| Abstract | The DOS for electrons bound to impurities in quantum wells of GaAlAs/GaAS heterostructures is calculated according to a realistic model that takes into account diagonal disorder due to dispersion in binding energy and off-diagonal disorder due to randomness in the transfer matrix element. The first one results from de dependence of the binding energy on the distance of the impurity from the interfaces. The seconde one results from teh structural disorder. A method is presented which applies when the ratio between the impurity layer thickness Delta and the most likely distance between impurities R is small. For instance, if the impurity concentration is 10 15 cm-3 and Delta = 100 A, Delta/R- 0.079. If the well width is in the range 100<=L<=600 A we find that both diagonal and off-diagonal disorder are of the same order, giving a band width in the range 1.2-5.5 meV. The off-diagonal disorder starts to become dominant as the number of impurities per unit area increases. |
