REDUCTION OF THE CONTACT RESISTANCE IN ORGANIC FIELD EFFECT TRANSISTORS COMPRISING PALLADIUM CONTACTS BY THE USE OF PHOSPHINES AND PHOSPHINES CONTAINING METAL

摘要

The invention relates to a semiconductor device comprising a semiconductor section consisting of an organic semiconductor material, a first contact for injecting charge carriers into the semiconductor section and a second contact for extracting charge carriers from the semiconductor section. A phosphine layer is located between the first contact and the semiconductor section and/or between the second contact and the semiconductor section. The phosphine acts as a charge transfer molecule, which facilitates the transfer of charge carriers between the contact and the organic semiconductor material. This enables the contact resistance between the contact and the organic material to be significantly reduced.
