(EN) A method for producing an electronic device with a layer structure and an electronic device
(FR) Méthode de fabrication d'un dispositif électronique à structure multicouche et dispositif électronique
Abstract
(EN) The invention relates to a method for producing a layer structure in an electronic device, especially in an organic light emitting device, the method comprising a step of producing the layer structure as a composite layer structure with free charge carriers generated by charge transfer between a first material and a second material, wherein the composite layer structure is provided as a stack of at least three non-mixed sub-layers made of the first material and the second material, respectively, wherein within the stack of the at least three non-mixed sub-layers each first material sub-layer is followed by an adjacent second material sub-layer and each second material sub-layer is followed by an adjacent first material sub-layer, and wherein the first material and the second material are selected to form a host-dopant material system for the electrical doping. The invention also relates to an electronic device.
