Conduction mechanism and the dielectric relaxation process of a-Se75Te25−xGax (x=0, 5, 10 and 15atwt%) chalcogenide glasses

Research on the physical properties of LiMn0.5Fe2O4 spinel ferrites by the combination of optical, magnetic, and dielectric behaviors

“…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.…”

Optical and dielectric properties of silver-substituted ZnAl2O4 spinels synthesized using a sol-gel auto-combustion method

“… 44 Since dipoles are not able to orient themselves at low temperature, the increase in ε ′ with temperature is associated to the fact that orientation polarization is related to the thermal motion of molecules. 45 …”

“…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 modied Debye function given by the following expression: 46…”

AC CONDUCTIVITY AND DIELECTRIC PROPERTIES OF AMORPHOUS Se69Sn10Ge21-xSbx (6≤ x ≤14) GLASSY SYSTEM

“…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].…”
