“…This result may be due to the orientation of polarization, which is related to the molecule's thermal motion. 62 It is explained by the fact that the dipoles remain frozen and cannot orient themselves at low temperatures. 63 In the temperature range (>250 K), the dipoles can rotate loosely and the molecular interaction energy effect becomes lower than the thermal energy.…”

“…44 Since dipoles are not able to orient themselves at low temperature, the increase in 3 0 with temperature is associated to the fact that orientation polarization is related to the thermal motion of molecules. 45 The experimental data of the dielectric constant (3 0 ) were adjusted using the modied Debye function given by the following expression: 46…”
“…In the recent years the study of amorphous semiconductor glasses has become one of the interesting areas of research due to their technical applications such as memory switching devices, optical switching, electro-photography, solar cells and IR transmission devices [1][2][3][4]. Dielectric properties such as dielectric constant and dielectric loss are important in explaining the defect states and structure of glassy network [5].…”
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 dielectric parameters is studied to explore material’s nature.
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.
