Abstract
The 3d-transition metal impurities (Mn, Co, and Cu) incorporated into III-V zinc blende hosts (GaAs, GaP, or InP) exhibit well resolved excitation lines followed by a photoionization continuum in their infrared absorption spectra. They are associated with transitions from a "1s-like" ground state to various "p-like" excited states characteristic of a hole bound to a Coulomb center. Their spacings agree remarkably well with those predicted in the effective mass theory for single acceptors [A. Baldereschi and N. O. Lipari, Phys. Rev. B 9, 1525 (1974)] as expected for 3d-transition metal ions substitutionally replacing the group III cations of the host. The shape o...
