Abstract
A surface of a copper (Cu) electrode is modified by a combination of preliminary oxidation treatment and grafting of a bifunctional self-assembled monolayer based on fluorobiphenylthiol (FBPS) or biphenylthiol (BPS). Under these conditions, a dinaphtho[2,3-b:2',3′-f]thieno[3,2-b]thiophene (DNTT)-based diode exhibits high mobility (0.35 cm·V·s) due to the formation of an organized assembly of FBPS on copper oxide that has been partially reduced to CuO. This organization controls that of a semiconductor film. On the other hand, the same treatment of a copper electrode with BPS molecules does not function due to the disorganization of both the BPS self-assembled monolayer (SAM) and the DNTT film. These results suggest that a monolayer of dipole-oriented molecules lowers an injection barrier and determines the semiconductor organization, thereby improving the performance of derived electronic parts.
