Current densities of hole-only devices based on alpha-sexithiophene (α-6T) and N- N′ -diphenyl- N- N′ -bis(1-naphthyl)- 1, 1′ -biphenyl- 4, 4′ -diamine (α-NPD) increase 42 times at 1 V by rubbing α-6T with a Nylon cloth. Results of absorption spectroscopy with normal and oblique light incidence reveal that the rubbing induces a change from standing to lying orientations of α-6T in a film surface region. The increased current densities are attributed to enhanced α-6T -to- α-NPD hole injection due to the lying orientation.
