|Title:||Binding Energies And Intra-donor Absorption Spectra In Gaas-gaalas Quantum Wells|
|Author:||Carneiro Gleise N.|

|Abstract:||We present a variational calculation in the effective-mass approximation of the binding energies of shallow donors in a GaAs-GaAlAs quantum wells. The energies and variational wavefunctions associated with the 1s-like ground state as well as some excited states (2s, 2px,y, 2pz, 3s, 3px,y and 3pz-like) are obtained as functions of the position of the impurity in the well. The intra-donor transition strengths and the infrared absorption spectra are calculated and results compare well with previous theoretical and experimental work.|
