beta-NMR in II-VI semiconductors

beta -active probe nuclei are implanted in nominally undoped ZnSe crystals. beta -radiation detected nuclear magnetic resonance (beta -NMR) studies ar e described for two different probe nuclei, Li-8 and B-12. This way, the im plantation behavior of two "opposite" dopants, one acceptor (Li) and one do nor (B) can be characterized by the same microscopic technique. Such charac terizations are attempted in terms of the structure of intermediate or fina l lattice sites, defect charge states, or the kinetics of defect reactions and site changes.
