| Abstract: | We calculated the binding energies of excitons in GaAs/A1_xGa_(1-x)As and In_(1-x)Ga_xAs/GaSb_(1-y)As_y quantum wells using a varitional method. The variations of binding energies with the well width and well depth was obtained. They present qualitative differences for these two kinds of quantum well structures. |
