GaAs/Al, Gal-As, have been theoretically calculated in the presence of impurity. In this regard, the effect of dot radius, stoichiometric ratio, impurity and in- cident optical intensity on the refractive index changes have been in- vestigated for the transitions between higher energy states, i.e., Is-1p, 1p-1d and 1d-lf. The results show that these parameters have a great influence on the refractive index changes.en10.2528/PIERM11080903info:eu-repo/semantics/openAccessArticle217792Q3
