Patent ID: 8901547

Claim:
A light-emitting transistor comprising a stacked structure, the stacked structure comprising: a substrate; a gate electrode; a channel layer comprising one or more organic sublayers, the one or more organic sublayers comprising: a first sublayer comprising an electron-transporting semiconductor material, a second sublayer comprising a hole-transporting semiconductor material, and a third sublayer comprising an electroluminescent semiconductor material; a dielectric layer positioned between the gate electrode and the channel layer; and a hole electrode and an electron electrode being spaced apart from each other at a planar distance defining the length (L) of a channel region therebetween, each of the hole electrode and the electron electrode being positioned either within the channel layer or on top of a first side of the channel layer, wherein the hole electrode is positioned away from a second side of the channel layer at a distance d1 and the electron electrode is positioned away from the second side of the channel layer at a distance d2 that is different from d1.
