摘要：
DC-conductivity of the nanocomposites consisting of ferroic nanocrystals NH2(C2H5)(4)CoCl2Br2 (TEA-CCB) incorporated into the polymer PMMA matrices is investigated. The investigations are performed for different number of nanocrystallite chromophores and thickness of the samples. The thickness of the nanocomposite films was varied within 0.44-0.48 mu m. The measurements were done at different temperatures and different applied voltages. As a dominant mechanism thermoemission was considered, which is determined by temperature of the samples.. The gold electrodes were used as principle electrodes. The observed phenomena were explained within a framework of hopping between the trapping levels and possible contribution of self-trapped excitons. (C) 2010 Elsevier B.V. All rights reserved.
