N2 - Oligomers of thiophene α-5T and α-6T were synthesized and vacuum evaporated as thin solid films onto platinized glass slides. They all behave as p-type semiconductors, and good rectifying barriers were obtained at α-nT/Ag junctions. Current-voltage and capacitance-voltage measurements were made, and allowed to determine electronic parameters of the organic semiconductors, such as mobility and doping level. Their values are compared to those of a polymethylthiophene (PMeT)/Ag diode. It appears that, due to their lower concentration of structural defects, well-defined oligomers present some advantages over polymers as far as their utilization to molecular electronics is concerned.
