Abstract
An analysis of available data for 20 wurtzite compounds of the type shows that the stability as compared with zinc blende is closely connected with deviations of the ratio from the ideal value of 1.633. A simple qualitative model is proposed to account for this feature. The variation in is then correlated with the charge parameter , where is the (effective) valence, Phillips's electronegativity difference, and the plasma energy of the free-valence-electron gas. The results indicate that may be predicted with an uncertainty of 0.1%.
