Abstract

The oriented ingots of isostructural compounds Sn~2~SbS~2~I~3~ and Pb~2~SbS~2~I~3~ were prepared using a modified Bridgman method. The lattice parameters of the prepared orthorhombic compounds have been determined by a X‐ray powder diffraction analysis. From the spectral response of the photoconductivity the following values for the forbidden zone of the prepared sulfides‐iodides were found: E~g~(Sn~2~SbS~2~I~3~) 1.5 eV, E~g~(Pb~2~SbS~2~I~3~) = 2.0 eV.

I-V characteristics of sandwiched Al-Sb,O,-A1 structures have heen studied for different thicknesses. The current-voltage curves in general exhibit three regions, ohmic, non ohmic and breakdown regions. The breakdown voltage increases whereas the dielectric strength decreases with increase in Sb,O,
