Thermal, ferroelastic, and structural properties near phase transitions of organic–inorganic perovskite type [NH 3 (CH 2 ) 3 NH 3 ]CdBr 4 crystals

C in the organic chains are more flexible at these temperatures. Based on these results, the physicochemical properties of the cation and anion during the III-II-I phase transitions were discussed. This study was conducted to improve the relatively weak thermal stability compared to the high efficiency for a variety of applications.
