ZnO films grown by atomic layer deposition for organic electronics

In this review, we analyze the properties of zinc oxide (ZnO) films grown by atomic layer deposition (ALD) crucial for organic electronics applications. We show the examples of such applications in hybrid organic-ZnO p–n junctions as well as in devices where conductive ZnO- and aluminum-doped ZnO films are used as transparent electrodes. Additionally, the relevant issues like energy-gap engineering in ZnO:Al films alloyed with magnesium or the long time stability of organic devices with ZnO passivation layers will be considered.
