Abstract
A semiconductor device includes a semiconductor path, the semiconductor path including an organic semiconductor material, a first contact to inject charge carriers into the semiconductor path, a second contact to extract charge carriers from the semiconductor path, and a layer including phosphine arranged between the first contact and the semiconductor path and/or between the second contact and the semiconductor path. The phosphine in the layer acts as a charge transfer molecule which makes it easier to transfer charge carriers between contact and organic semiconductor material. As a result, the contact resistance between contact and organic semiconductor material can be reduced considerably.
