Organic Photoconductors were studied since the early 19th century and extensive research work had been made in exploring the electrical properties of organic materials. In this book, we studied the effect of change in dielectric constant with increase in concentration of (SrTiO3) nano particles. Similarly the results obtained from LCR Impedance analysis was compared with different results to compare feasibility of LCR measurement technique and its future prospects in characterization of new class of Organic dielectrics.
