Infrared transitions between hydrogenic states in GaInNAs/GaAs quantum wells

Abstract

The effects of nitrogen and indium concentrations on the [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]-like donor impurity energy states in a single [Formula: see text] quantum well (QW) are investigated by variational approach within the effective mass approximation. The results are presented as a function of the well width and the donor impurity position. It is found that the impurity binding and transition energies depend strongly on the indium concentration while depends weakly on the nitrogen concentration.
