Electro-conductive properties of cadmium octanoate composites with CdS nanoparticles
Electrical properties of mesogenic cadmium octanoate composites containing
 CdS nanoparticles (NPs) have been studied for the first time. Semiconductor CdS
 spherical NPs (sizes of 2.5 nm) were chemically synthesized in the thermotropic ionic
 liquid crystalline phase (smecti...

| description | Electrical properties of mesogenic cadmium octanoate composites containing
CdS nanoparticles (NPs) have been studied for the first time. Semiconductor CdS
spherical NPs (sizes of 2.5 nm) were chemically synthesized in the thermotropic ionic
liquid crystalline phase (smectic A) of cadmium octanoate that was used as nanoreactor.
We compared the electrical properties of both clean matrix and nanocomposite to clarify
the role of semiconductor CdS NPs with different concentrations. We have investigated
electrical characteristics at different temperatures, which correspond to the different
phases of the composites. The conductivity of nanocomposites has an activation nature
both in anisotropic glassy and smectic A phase. The conductivity of the nanocomposite
along the cation-anion layers is by two orders of magnitude higher than that across the
cation-anion layers, which confirms anisotropy of the nanocomposite regardless of the
phase of material. In the glassy phase, the electronic type conductivity is observed.
Increasing the nanoparticles concentration brings additional free charge carriers or
increases their mobility. For the smectic A phase, increasing the CdS NPs concentration
brings additional traps for the carriers that travel in plane of the cation-anion layers. On
the other hand, the nanoparticles deform the cation-anion layers and increase the mobility
of carriers across the layers.
