abstract

  • AbstractBecause of a strong prevacancy effect in cadmium the assumptions of the trapping model seem to be fulfilled rather badly. Therefore the formation enthalpy of monovacancies is also determined by methods using the trapping model only to some extent or not at all. H is obtained as (0.39 ± 0.04) eV (from the trapping model), H = (0.42 ± 0.02) eV (from the inflection point), and H = (0.45 ± 0.08) eV (from the threshold temperature).
