Abstract : The internal electric field distribution has been measured in photoconducting CdS single crystals using the linear electrooptic effect. The electrooptic effect in CdS is discussed in relation to the optical probe technique used. The experimental results show a nearly homogeneous field distribution in the crystals for applied fields below the threshold for acoustoelectric oscillations, while a high field region was created near the anode and a low field region in the cathode area for fields above the threshold field. The reproducibility from sample to sample was rather poor. The linear electrooptic constant was calculated from the experimental results: r(subscript 113) - r(subscript 333) = 2.7 x 10 to the -12th power m/V at the optical wavelength 6328 A. Intensity variation due to light absorption in the crystal and vibrations in the fundamental mode, was observed in some low conductivity samples. (Author)
