      More Details Abstract Fulltext PDF

      The electrical resistivities of organic charge transfer complexes namely dithionaphthalene-iodine (1:1), anthracene-trinitrobenzene (1:1), pyrene-2I2 and benzidine-tcnq (dichloromethane) have been studied upto 2–8 GPa pressure. An increase in the electrical resistivities shows that the conduction is due to a hopping mechanism involving localized levels near the band edges or is trap-limited. Pressure can increase both the density of defects and intermolecular orbital overlap as opposite effects.

      More Details Abstract Fulltext PDF

      Dielectric constant and dissipation factor of lead phthalocyanine have been experimentally studied here as functions of frequency and temperature. Dielectric constant increases by one order of magnitude with temperature showing pyroelectric behaviour. It is explained that molecular distortion leads to increased dielectric constant.
