摘要：

We find that the phase coherence factor derived from Hall effect measurements of single-crystal thin-film field-effect transistors of pentacene, which relates the intrinsic charge transport with the phase coherence, has a strong correlation with the thermal fluctuations of transfer energies between neighboring molecules. This observation also holds true for other organic semiconductors such as tetracene, dianthrathiophene (DAT)-V, and dinaphtho[2,3-b:2',3'-f] thieno[3,2-b] thiophene ( DNTT). This gives us clues for constructing flexible molecular systems with high carrier mobility. (C) 2015 AIP Publishing LLC.
