Project Abstract

In this work, for a double quantum well which has the Lennard-Jones potential, the ground and some excited donor impurity binding energies and the total absorption coefficients, including linear and third order nonlinear terms for the transitions between the related impurity states with respect to the structure parameters and the impurity position as well as the electric (or magnetic) field strength will be investigated theoretically. The binding energies will be obtained by using the variational method in the effective-mass approximation and the optical transitions between any two donor impurity states were calculated by using the density matrix formalism and the perturbation expansion method. Finally, the obtained results will be compared with the previously results of different shaped double potential quantum wells.
