    Abstract: An embodiment of the present invention pertains to an electrode that includes a metal oxide layer, and a conductive layer on that metal oxide layer. The metal oxide layer is an alkali metal oxide or an alkaline earth metal oxide that is formed by: (1) decomposing a compound that includes (a) oxygen and (b) an alkali metal or an alkaline earth metal, or (2) thermally reacting at least two compounds where one of the at least two compounds includes the alkali metal or the alkaline earth metal, and another one of the at least two compounds includes oxygen. The metal oxide layer can also be formed by thermally reacting at least two compounds where one of those compounds includes (a) oxygen and (b) an alkali metal or an alkaline earth metal.

    Abstract: In an embodiment of the invention, an electronic device includes an interfacial layer with traps. This interfacial layer is between an electrode and an organic layer, and if the electrode was adjacent to the organic layer, the energy barrier between these two layers is such that the current through the organic layer is limited by charge injection into this layer rather than the transport properties of the organic layer. The traps are used to accumulate charges of one charge type (e.g., either electrons or holes) within the interfacial layer. By accumulating charges, the bands of the interfacial layer are bent so that charges can tunnel from the electrode to the organic layer thus increasing the efficiency of the electronic device and allowing organic layers to be used within an electronic device that otherwise would be too inefficient for use in that device.
