Abstract:The glassy network system under investigation is prepared by using melt quench technique. The ac conductivity and dielectric behavior studied in ac frequency range (500Hz–1MHz) below glass transformation region. The correlated barrier hopping (CBH) model is used for interpreting the relation between the frequency exponent and temperature. The equation based on the Guintini model gives the value of maximum barrier height from the dielectric measurements. The compositional variation of conduction mechanism and d… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
