Dielectric impedance and modulus spectroscopic analysis of few melaminium compounds for electrical applications

Abstract

Single organic crystals with good photochemical and thermal stability newlineplay an important role in growing efficient Nonlinear Optical materials that has newlineapplication in optical data storage, communication, and Opto-electronic newlinetechnologies. In addition to the low dielectric constant, these materials also newlinehave high electro-optic coefficient and exhibit optimal response rate. It is well newlineknown that the intrinsic optical properties of graphene result from the newlinedelocalized van der Waals bond. The role of nonlinear optical properties in newlineorganic molecules is due to its large second harmonic generation response. newlineTo provide a practical overview of dielectric spectroscopy which is newlinethe study of the movement of electronic dipoles (e.g dipolar newlinemolecules) in the presence of an electric field. newline To grow the single crystals of melamine with perchloric acid, newlinetrichloroacetic acid, p-nitrophenol and m-nitrophenol additives. newline To characterize the grown crystals by dielectric characterization newlinetechniques and to study the various properties like electrical newlineconductivity, elastic modulus, complex imdepance, conductivity etc newline To provide a brief history and perspective on the importance of newlinemelamine crystals by expanding its possibilities that exist for future newlinedevelopments through dielectric spectroscopy. newline
