Abstract:
1. An organic electronic memory component comprising an electrode and a counterelectrode, and an organic layer arrangement disposed between said electrode and counterelectrode and in electrical contact therewith, wherein the organic layer arrangement comprises the following organic layers: an electrode side charge carrier transport layer and a counterelectrode side charge carrier-blocking layer and disposed between said electrode side charge carrier transport layer and counterelectrode-side charge carrier-blocking layer a memory layer region comprising a first charge carrier-storing layer and a second charge carrier-storing layer between which first charge carrier-storing layer and a second charge carrier-storing layer is disposed a charge carrier barrier layer, wherein the electrode is a cathode and the counterelectrode is an anode, the electrode-side charge-carrying transport layer is a cathode-side electron transport layer, the counterelectrode-side charge carrier-blocking layer is an anode-side electron-blocking laver, the first charge carrier-storing layer is an electron-storing layer, the second charge carrier-storing layer is a second electron-storing layer, and the charge carrier barrier layer is an electron barrier layer, and wherein the LUMO level of the cathode-side electron transport layer lies energetically higher than the LUMO level of the first electron-storing layer, which first electron-storing layer is disposed adjacently to the cathode-side electron transport layer; the LUMO level of the anode-side electron-blocking layer lies energetically higher than the LUMO level of the second electron-storing layer, which second electron-storing layer is disposed adjacently to the anode-side electron-blocking layer; and the LUMO level of the first electron-storing layer and the second electron-storing layer lies energetically lower than the LUMO level of the electron barrier layer.
