Study of Conduction Mechanisms and Relaxation Processes in NiCl sub 2 -PVA Composites

摘要

Electric conduction measurements were made at different temperatures and fields on thin films of NiCl sub 2 -PVA composites prepared by casting. The conduction is assumed to be generally ionic in nature and polarization contribution is suggested to operate mainly at higher temperatures. Space-charge limited conduction and relaxation phenomena have been observed. The obtained results made it possible to determine a complete set of conduction parameters including carrier mobility, carrier concentration, traps density, Fermi energy, activation energy, etc. 32 refs, 14 figs, 4 tabs.
