Abstract :
A relaxation effect in natural crystals of cubic ZnS, seen during d.c. measurement of the electro-optic coefficient at a wavelength of 0.6328 ¿m, is explained in terms of photo-electrically induced space charge. The effect is not evident at low light levels, or at wavelengths remote from the absorption edge of this semiconductor material.
