Abstract
We have synthesized Sb1-xBixTeI (where x = 0.1, 0.4 and 0.9.). The str uctural variation, electrical resistivity, diffuse reflectance spectro scopy and surface morphology of Sb1-xBixTeI have been studied. The com pounds crystallize with the triclinic symmetry. The temperature depend ence of electrical resistivity exhibits semiconducting behaviour. The activation energy and band gap of pure SbTeI are found to be 0.37 and 0.73 eV, respectively.
