Abstract:
1. An organic field-effect transistor comprising: a gate electrode, a drain electrode, and a source electrode; an active layer comprising an organic material, wherein the active layer forms an electric conducting channel during operation; a dielectric layer, wherein the dielectric layer is arranged between the active layer and the gate electrode; and a dopant material layer, wherein the dopant material layer comprises a molecular dopant material, wherein the molecular dopant material comprises at least one molecule comprising two or more atoms, and wherein the at least one molecule is an electrical dopant for the organic material of the active layer, wherein a boundary surface region comprises an area between the active layer and the dielectric layer, and wherein the dopant material layer is arranged adjacent to the boundary surface region, and wherein the dopant material layer is arranged at a distance of about one to about three monolayers from the boundary surface region.
