Claim Text:
1. A zener diode comprising one electrode, one counter electrode, and an organic layer arrangement, wherein the organic layer arrangement is in electrical contact with the electrode and counter electrode, and wherein the organic layer arrangement comprises: an n-doped charge carrier injection layer, wherein the n-doped charge carrier injection layer comprises a mixture of a first organic matrix material and an n-dopant, a p-doped charge carrier injection layer, wherein the p-doped charge carrier injection layer comprises a mixture of a second organic matrix material and a p-dopant, wherein the p-doped charge carrier injection layer is arranged closer to the counter electrode than the n-doped charge carrier injection layer, wherein the first organic matrix material and the second organic matrix material are different matrix materials, and an electrically undoped organic intermediate layer, wherein the electrically undoped organic intermediate layer is arranged between the n-doped charge carrier injection layer and the p-doped charge carrier injection layer, and the electrically undoped organic intermediate layer is made of one or more organic materials, the one or more organic materials being different from the first organic matrix material and the second organic matrix material.
