AbstractAbstract
[en] Using copper (a fast diffusing, multivalent acceptor impurity in Ge) it was shown that hydrogen can form complexes with multivalent acceptors. Hydrogen is incorporated in the Ge single crystal during its growth from a melt in a H2 atmosphere. By analogy with the interaction between lithium and multivalent acceptors two acceptor like complexes (Cu-H and Cu-H2) were found. Using Photothermal Ionization Spectroscopy and Hall effect the following energy levels are assigned: Cu-H: E/sub V/ + 17.5 meV and E/sub V/ + 170 +- 20 meV and Cu-H2: E/sub V/ + 17.0 meV. According to the model the Cu-H3 complex is neutral. Consequences for the performance of large volume radiation detectors are discussed
