摘要
A new organic–inorganic ABX_(3)perovskite-type semiconducting hybrid,N-methylpyrrolidinium trichlorocadmate(MPCC),has been synthesized.It is found that MPCC exhibits semiconducting behaviour with an optical bandgap of∼4.65 eV,as well as remarkable dielectric switching properties.It displays a structural phase transition(SPT)at T_(c)=254 K,being confirmed by DSC and specific heat measurements.
