摘要

The electrical properties of microcrystalline wax have been studied as a function of temperature, field and pressure by sandwiching the different thicknesses of the sample between copper electrodes. The ln σ versus 1/T plots have two regions pertaining to high and low temperatures, respectively. Activation energy for conduction indicates the predominance of electronic conduction mechanism in both the regions. The plots of (ln J versus ln E) have three regions known as low, intermediate and high field regions. It is found that Ohms law was applicable in low field region, the space charge limited conduction in intermediate field region and the Schottky or Poole-Frenkel conduction mechanisms in high field region as confirmed by ln J versus E~(1/2) plots, σ versus P plots have transition pressure below which conductivity increases and above which conductivity decreases with pressure.
