Abstract
The present invention relates to methods and apparatus for producing an electronic device, such as an organic light-emitting diode (OLED), having an electrode with enhanced injection properties. An example method according to the invention comprises the steps of providing an electrode, depositing a first layer of molecular charge transfer material on the electrode, and cross-linking the molecular charge transfer material. With the method according to the invention, an OLED with higher light efficiency, lower operating voltage, and longer lifetime can be produced. The present invention further relates to an electronic device having an electrode with enhanced injection properties.
