Abstract
We present a calculation of the absorption coefficient for the intraimpurity transitions between the first hydrogenlike donor states (n≤3) existing in a quantum well (QW) of finite width, for uniform, Gaussian-, and δ-like dopings. The eigenstates are obtained using a variational formulation with Slater-type functions. In this way we obtain the states 1s, 2s, 3s, 3, and 3d. The obtained wave functions allow us to calculate the oscillator strengths of the transitions, resulting in the absorption coefficient, which is in good agreement with the experimental values available in the literature.
