Abstract
A semiconductor device comprises a substrate, a first hole-transporting layer over the substrate, a first electron-transporting layer on the first hole-transporting layer, and a second hole-transporting layer over the first electron-transporting layer. At least one of the first electron-transporting layer and the second hole-transporting layer has an organic component. The device is characterized by one of the following: a metal oxide layer present on the first electron-transporting layer, wherein a second electron-transporting layer is on the metal oxide layer, wherein the second hole-transporting layer is on the second electron-transporting layer, or the second hole transporting layer has a first p-doped hole-transporting surface present on the first electron-transporting, layer and a second p-doped hole-transporting surface facing away from the first p-doped hole-transporting surface, or the first electron-transporting layer is on a top surface and on sidewalls of the first hole-transporting layer.
