Electrical response of organic molecule supported preformed and in situ formed antimony sulfide nanoparticles under frequency conditions

Abstract

A complexation route mediated synthesis of orthorhombic antimony sulfide nanoparticles is described in this report where uniformly distributed particles within the size range of 2–12 nm are stabilized within the aniline matrix. The organic–inorganic hybrid system was investigated for dielectric capacitance and electric field-induced polarization performances under varying temperature and frequency conditions. The AC-conductivity revealed a correlated barrier hopping conduction mechanism in the hybrid system. A fatigue free polarization was achieved under the electric field of 9 kV mm⁻¹ for the preformed antimony sulfide system with a stable value of 0.18 μC cm⁻². The in situ dielectric capacitance and field dependent polarization measurements were also performed for the in situ synthesized antimony sulfide using the antimony–aniline complex as the precursor.
