Structural, optical, and electrical properties of doped samarium chromite

Abstract

The structural, optical, and electrical properties of SmCrO 3 doped on the two cation sites were studied using electron probe x-ray microanalysis, ellipsometry, and conductivity measurements. The results for the Sm 0.8 Ca 0.2 Cr 0.92 Cu 0.08 O 3 solid solution demonstrate that hydrogen reduction at 1270 or 1620 K produces significant microstructural changes and leads to Ca 2+ or Cu 2+ segregation at grain boundaries. Both doping and hydrogen reduction influence the electrical and optical properties of samarium chromite.
