✦ Synopsis

Different

thermal activation energies of dark conduction in the ohmic and square-law regions have been measured for anthracene.

The ohmic activation energy has been interpreted in terms of localised dominant esponcntially distributed hole and dominant electron levels within the band-gap.

The square-law activation energy is attributed to shallow trapping.
