| Abstract: | 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 exponentially distributed hole and dominant electron levels within the band-gap. The square-law activation energy is attributed to shallow trapping. |
