In semiconductors with bipolar photoconduction the measurements of the electrical conductivity and the Hall effect are not sufficient for the determination of the carrier densities and mobilities. In this case the acoustoelectric effect may be used a

Single crystals of silicon telluride, which has an unusual 2:3 stoichiometry, have been grown by a chemical vapor deposition technique. A photoluminescence level at 1.3 eV has been found as well as strong EPR signals, suggesting defects in the crysta
