Abstract

A series of n-type oxide double perovskite semiconductors, Sr₂In_1-xSn_xSbO₆ (0 ≤ x ≤ 0.3) has been synthesized; Sn⁴⁺ partially substitutes for In³⁺. ¹²¹Sb and ¹¹⁹Sn Mössbauer spectroscopy are employed to investigate the B-site cation ordering because this issue cannot be resolved by conventional diffraction techniques alone. Rigid ordering between In³⁺/Sn⁴⁺ and Sb⁵⁺ sites is revealed by the spectroscopic method, and hence in combination with the structural parameters extracted from the XRD structural refinements, the crystallographic structure of this series of compounds is depicted. The temperature dependent magnetic susceptibilities, band gaps, and carrier type are characterized, and the calculated band structure is presented.
