摘要：

We show calculations for far-infrared absorption of shallow-donor impurities in quantum well wires in the presence of an external magnetic field. The wave functions and the eigenvlaues are obtained in the effective-mass approximation by using an extended variational approach in which the ground and excited magneto-impurity states are simultaneously obtained. We investigate the allowed intra-donor transitions for radiation circularly polarized in the plane perpendicular to the magnetic field. We Present results for the absorption coefficient as a function of the photon energy for several field strengths and arbitrary impurity positions. (C) 2008 Elsevier Ltd. All rights reserved.
