The effect of fabrication environment on current-voltage (I-V) characteristics of nominally symmetric Mg:Ag/Alq3/Mg:Ag structures was investigated. The structure fabricated under stringent vacuum conditions exhibits symmetric I-V characteristics. The results imply that the contacts formed by evaporating Mg:Ag on Alq3, or Alq3 on Mg:Ag, are equally efficient and that the perturbation caused to the organic layer by the top deposited metal has no significant impact on the injection process.
