## Description

- description: Cesium-tin-bromide perovskite (CsSnBr3) has focused on as a candidate
    material for all-inorganic perovskite solar cell and thermoelectric energy converter
    because of its optical, electrical, and thermal properties. On the other hand,
    the electrical properties have not been clarified yet because of several inconsistent
    reports. In this paper, we produced CsSnBr3 bulk from a melt using the precursor
    powder prepared by a mechanochemical process. From powder X-ray diffraction analysis,
    main phase of the precursor was CsSnBr3 perovskite, and minor impurities were
    Cs2SnBr4 and CsSn2Br5. Although main phase of the bulk produced from a melt was
    CsSnBr3, small amount impurity, CsSn2Br5 was confirmed. From the electrical conductivity
    (σt) measurement, irreversible temperature dependence of σt was observed at first
    time increasing temperature. The conductivity measured from room temperature to
    443 K at the first time showed metallic behavior. On the other hand, the temperature
    dependence is changed into opposite with decreasing temperature. At this operation,
    σt decrease with decreasing temperature. This semiconductor like behavior was
    found to be reversible after first increasing temperature operation. These results
    indicate that post anneal as well as production process of CsSnBr3 would be important
    to control its electric property.
