Abstract

AbstractThe 0.11 eV Mn acceptor has been investigated using different kinds of FΠR techniques, Zeeman spectroscopy, and photoluminescence. The results clearly fits into the Зd5+ shallow hole model for Mn° and show that the 0.11 eV level originates from the io-nization of a neutral, substitutional Mn acceptor at a Ga-site. The ground state binding energy obtained from the effective-mass like excited states is 112.4 meV.
