Physicochemical study of SmTe-In2Te3 and SmTe-InTe systems

SmTe-In2Te3 and SmTe-InTe quasi-binary joins were studied using physicochemical methods. The SmTe-In2Te3 system forms two compounds, SmIn2Te4 and SmIn 4Te7, which melt

Synthesis of copper, silver, and samarium chalcogenides by mechanical alloying

CuInX2 (X = S, Se, Te), Ag2S, Ag2Se, Ag3Te2, Ag1.9Te, AgCuSe, Sm3Se4, Sm2Se3, and SmTe were synthesized by a mechanical alloying method, using a high-energy planetary ball mill. The compounds were obtained by milling mixtures of the elements with desired ratios in agate or Cu-Be vials for 60-180 min. Copyright

BAND EDGE EXCITION SPECTRA IN Sm MONOCHALCOGENIDES.

Reflection spectra have been measured on semiconducting SmS, SmSe and SmTe single crystals at 2 K in the photon energy region from 3 to 6 ev. From a comparison of the spectra in these Sm monochalcogenides with those in BaS and BaSe, the reflection peaks observed in this photon energy region are identified as the Wannier excitons associated with the band-edges at the X-point and the GAMMA -point. Temperature dependence of the reflection peaks and the electroreflectance spectra of SmSe support this identification. The energy band structure of semiconducting Sm monochalcogenides is discussed on the basis of the observed exciton spectra.
