Abstract :
Electrical conductivity measurements of zone-refined acenaphthene were carried out as a function of temperature and field. The analysis of results in terms of I-V characteristics, log J vs. T, log σ vs. 1/T, Richardson plots Schottky plots, and Fowler-Nordheim plots reveals that the current density is predominantly temperature-dependent at higher temperatures and is temperature-independent (or less dependent) in the lower temperature range. This suggests that electrical conduction in acenaphthene takes place via Schottky emission and tunneling. Schottky emission operates at higher temperature, whereas the tunneling mechanism and hopping operate at lower temperature
