Synthesis, thermal analysis and structural characterization of the ternary compound Ag2SnTe3
(SaberULA, 2019-05-29)
The ternary compound Ag2 SnTe3 has been synthesized and investigated by means of X-ray powder
diffraction and its structure has been refined by the Rietveld method. The thermal differential
analysis indicates a melting ...

Urbach’s tail in the absorption spectra of Cu2GeSe3 semiconducting compound
(SaberULA, 2019-05-29)
In the present work we report on the analysis of the Urbach’s tail in pure and Mn-doped Cu2GeSe3
samples having small deviation from its ideal stoichiometry. It is found that the high values of the
phonon energy h?p ...
