Resumen

We report on results for the electronic structure of the isolated substitutional and interstitial copper impurities as well as of the interstitial-substitutional copper pair complex in germanium. The SCF spin-polarized calculations are carried out in order to obtain, for each system, the one-electron energy gap levels, total spins, and acceptor and donor transitions. Based on the results, microscopic models are proposed to describe the electronic states of the Cus, Cui, and Cui-Cus impurities in germanium.
