摘要

Poly(3-hexylthiophene), (P3HT), is widely used in organic semiconductor applications. Time of Flight measurements on P3HT displayed three distinct hole transport pathways with corresponding mobilities above 10(-4), between 10(-5) and 10(-4) and below 10(-5) cm(2)V(-1)s(-1) over a range of sample thickness (1.1 mu m-4.2 mu m), and electric field (2.4 MVm(-1) to 37.7 MVm(-1)). The space-charge limited current (Mott-Gurney) device mobility was in agreement with that obtained for the fastest route (10(-4) cm(2)V(-1)s(-1)). The transport pathways were distinguished using a dispersive transport plot of reciprocal transit time versus electric field to thickness ratio and are described by single (pseudo dispersion) parameters: alpha(t1) = 0.97, alpha(t2) = 0.73 and alpha(t3) = 0.62. The P3HT displayed 3 M mass peaks obtained by Gel Permeation Chromatography, which are the most likely cause of the three pathways. The dispersive transport analysis used here offers clearer distinction between pathways than Poole-Frenkel plots and offers a full mobility description, including the dependence on sample thickness, making it suitable for general application.
