Abstract
Semiconduction activation energies of adenine, guanine, thymine and uracil complexes with acridine orange dye at various dye concentrations were measured in both Ohmic and space charge limited (SCL) current regimes. The behaviour of the complexes is non-extrinsic at high dye concentrations but extrinsic at low dye concentrations. Dominant electron and hole levels are shown to depend also on dye concentration. Various transport parameters have been evaluated.
