    Abstract

    We investigate the carrier injection and transport in individual para-hexaphenylene nanofibers by electrical transport measurements at different temperatures. The injected current shows much weaker temperature dependence than what would be anticipated from a simplistic model that considers the injection barrier height equal to the difference between the metal electrode work function and the HOMO energy level of the organic semiconductor. Semiquantitative modeling suggests that the weak temperature dependence is due to injection into a distribution of states rather than into a single energy level. This disorder induced energy level broadening could be caused by the electrode deposition process
