Abstract
A method of modifying a work function of a conductor surface for use in organic light emitting devices. A plasma treatment is performed on the conductive layer. The plasma treatment employs a mixing gas comprising a nitrogen-containing gas for decreasing the work function and an oxygen-containing gas for increasing the work function. A flow ratio of the nitrogen-containing gas to the oxygen-containing gas is controlled to modify the work function.
