    We show that quantitative information on the electrical deactivation of doping can be obtained by combining the results of positron annihilation, secondary ion-mass spectrometry and capacitance–voltage measurements. We have applied this method to study the nitrogen doping in ZnSxSe1−x and MgyZn1−ySxSe1−x and we conclude that in addition to isolated acceptor impurities NSe−, nitrogen atoms are also situated at high concentrations in compensating donors, most probably in (ZniNSe)1+ and (VSeNSe)1+ pairs, or in electrically neutral form, leading to electrical compensation of p-type material.
