The effect of radiation on electric conduction in n-hexane

At fields up to 80 kv/cm, the dark conduction obeys Ohm´s law, and the gamma-ray induced and the ultra-violet photo-injected currents do not saturate for a wide range of temperatures. The induced and the injected currents are proportional to the intensity of radiation. lt is suggested that the dark conduction is associated with the presence of irremovable impurities, and that the small fluctuation of conduction current is attributed to the electrons being irregularly trapped and thermally released during their drift toward the anode. The factors influencing the mobilities of positive and negative charge carriers are discussed.
