Abstract:
1. An electroluminescence generating device comprising: a. a channel comprising at least one layer of an organic semiconductor material, said organic semiconductor material being a polycrystalline semiconductor-material, said channel being able to carry both types of charge carriers, said charge carriers being electrons and holes, said channel being realized by one layer of organic semiconductor or by several coplanar layers of organic semiconductors; b. an electron electrode, said electron electrode being in contact with said channel and positioned on top of a first side of said channel layer or within said channel layer, said electron electrode being able to inject electrons in said channel layer; c. a hole electrode, said hole electrode being spaced apart from said electron electrode, said hole electrode being in contact with said channel and positioned on top of a first side of said channel layer or within said channel layer, said hole electrode being able to inject holes in said channel, said electron electrode and said hole electrode being positioned in an horizontal plane along said channel; d. a control electrode positioned on said first side or on a second side of said channel, said control electrode being suitable for controlling the charge injection, the current flow and the charge recombination between the electron electrode and the hole electrode; whereby said electroluminescence generating device being able to emit light by applying an electrical potential difference between said electron electrode and said hole electrode, characterized in that at least one of said electron electrode and said hole electrode comprise at least one different material which is not comprised in the other one.
