Sažetak

Electrical conduction of sodium acetylacetonate compound [Na (ac, ac)] was measured as a function of temperature, field and time. The current-time characteristic have been studied in the voltage range 2-300 V and in the temperature range 20-100 °C. The I-V characteristic and dc conductivity were also studied and discussed on the basis of ionic conduction. The current-time tendency after an application of dc voltage as well as the current maximum observed by the reversal of applied voltage polarity are discussed in the light of the orientation of electric dipole and space-charge mechanisms. The obtained results made it possible to determine a set of conduction parameter including carrier mobility µ, mobile ion density n, activation energy of the conduction Ec and activation energy concerning the transport phenomenon Eµ.
