Abstract
We report on Perturbed Angular Correlation measurements in polycrystalline In2S3 samples in the temperature range from 8 K to 1000 K where two different crystallographic phases β and α occur. As probes, implanted 111In nuclei have been used. The three observed EFGs are attributed to probes residing substitutionally in the different sulfur-octahedra and -tetrahedra of β-In2S3. A strong dam** between 150 K and 300 K has been attributed to EFG fluctuations following the 111In(EC)111Cd decay. The α-phase (above 680 K) is characterized by a different dynamical dam** of the perturbation functions, caused by mobile In atoms. Therefore, the semiconductor In2S3 shows, in two different temperature ranges, dynamical PAC-spectra which correspond to different types of mobile charge carriers. Since 111In is a self atom in In2S3, this compound is an ideal substance to study the charge transport phenomena by the PAC technique.
