New paper: White OLEDs with 4 nm metal electrode

In our new paper published in Applied Physics Letters entitled “White organic light-emitting diodes with 4 nm metal electrode“, we report on white OLEDs with ultra thin metal electrodes that replace ITO for the better. With close layers of only 4 nm thickness, the overall optical properties of these composite electrodes approach the ITO standard electrode system, whereas their mechanical performance is by far superior. Such electrodes are highly flexible and, in addition, allow for fabrication at any position within the vertical layer structure. Thus, their use is not limited to the bottom electrode function, but also they can be used as interconnects and/or transparent top electrodes.
