Abstract
An investigation of the optical properties of a hydrogenic donor in a disc-like parabolic quantum dot with magnetic field has been performed by using the matrix diagonalization method. The optical absorption coefficient between the ground (L = 0) and the first excited state (L = -1) have been examined based on the computed energies and wavefunctions. We found that the linear optical properties of the hydrogenic donor in QDs are strongly affected by the confinement strength and the magnetic field strength.
