Means for electrical contacting or isolation of organic or inorganic semiconductors and a method for its fabrication

摘要

In a means for electrical contacting or isolation of organic or inorganic semiconductors in electronic and optoelectronic devices, particularly thin-film devices, the means comprises a substrate ( 1 ) in the form of a contact material ( 1 a) or an isolating material ( 4 ). A charge transfer material ( 2 ) is provided patterned or unpatterned on or at the surface of the substrate and includes charge transfer components in the form of donors and/or acceptors. The charge transfer material forms a self-assembling layer ( 3 ) on one or more atomic and/or molecular layers. The charge transfer material ( 2 ) has a direct or indirect bond to the surface of the substrate ( 1 ) and further forms a charge transfer complex with a thereabove adjacently provided organic or inorganic semiconductor ( 6 ). The charge transfer material ( 2 ) then forms a donor or acceptor material in the charge transfer complex depending upon respectively whether the semiconductor ( 6 ) itself is an acceptor or donor material.
