Abstract
Official abstract text for this publication.
A transparent conductive electrode stack containing a work function adjusted carbon-containing material is provided. Specifically, the transparent conductive electrode stack includes a layer of a carbon-containing material and a layer of a work function modifying material. The presence of the work function modifying material in the transparent conductive electrode stack shifts the work function of the layer of carbon-containing material to a higher value for better hole injection into the OLED device as compared to a transparent conductive electrode that includes only a layer of carbon-containing material and no work function modifying material.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming an electronic device including a transparent conductive electrode stack, said method comprising: providing a layer of a carbon-containing material; and forming a layer of a work function modifying material on an exposed surface of the layer of carbon-containing material, wherein said layer of work function modifying material is a metal film or an array of metal dots, and said metal film or said array of metal dots are formed beneath the…
