Abstract: Muonium spectroscopy experiments are used to obtain detailed microscopic information about the electronic structure of the muonium impurity in II-VI compound semiconductors, used as model for isolated hydrogen. Donor and acceptor configurations are analysed, and the corresponding levels are discussed. Unique shallow donor behaviour in ZnO and the cadmium chalcogenides, contrastina with amphoteric behaviour in ZnSe and ZnS, is presented in the framework of a general model. (C) 2007 Elsevier B.V.
