Abstract
In the paper we present a unifying model for the dominant copper impurity in ZnO: Neutral copper atoms at interstitial sites with octahedral symmetry have the electron configuration 3dγ2 4s 1 4p 2. They undergo a weak dynamic Jahn-Teller coupling. The vibronic states are2 P,4 P and6 P. Electric dipole transitions coupled to vibration modes give rise to IR and visible absorption bands, showing vibrational progressions. The splitting factors of the various states are calculated by means of the Landé rule which is slightly modified by a reduction of the orbital momentum. The experimental findings concerning IR stimulated fluorescence and electrical conductivity can also be understood within the frame of this model.
